Method Detail

doesQueryFitFilterForm

public boolean doesQueryFitFilterForm(ApplicationUser user,
                                      Query query)

Description copied from interface: SearchService

Checks if a Query is capable of being shown on the simple (GUI-based) issue navigator edit screen.

Specified by:

doesQueryFitFilterForm in interface SearchService

Parameters:

user - the user who is executing the query.

query - the Query which to check that is displayable on the simple (GUI-based) issue navigator edit screen. Does not accept null.

Returns:

true if the query is displayable on the simple (GUI-based) issue navigator edit screen, false otherwise.

search

public SearchResults<Issue> search(ApplicationUser searcher,
                                   Query query,
                                   PagerFilter pager)
                            throws SearchException

Description copied from interface: SearchService

Search the index, and only return issues that are in the pager's range.

Note: that this method returns read only Issue objects, and should not be used where you need the issue for update.

Specified by:

search in interface SearchService

Parameters:

searcher - the user performing the search, which will be used to create a permission filter that filters out any of the results the user is not able to see and will be used to provide context for the search.

query - contains the information required to perform the search.

pager - Pager filter (use PagerFilter.getUnlimitedFilter() to get all issues).

Returns:

A SearchResults containing the resulting issues.

Throws:

SearchException - thrown if there is a severe problem encountered with lucene when searching (wraps an IOException).

searchOverrideSecurity

public SearchResults<Issue> searchOverrideSecurity(ApplicationUser searcher,
                                                   Query query,
                                                   PagerFilter pager)
                                            throws SearchException

Description copied from interface: SearchService

Search the index, and only return issues that are in the pager's range while AND'ing the raw lucene query to the generated query from the provided searchQuery, not taking into account any security constraints.

As the method name implies, it bypasses the security restrictions that would normally be applied when performing a search. As such, it should only be used for administrative tasks where you really need to know about ALL affected issues.

Note that this method returns read only Issue objects, and should not be used where you need the issue for update. Also note that if you are only after the number of search results use SearchService.searchCount(ApplicationUser, Query) as it provides better performance.

Specified by:

searchOverrideSecurity in interface SearchService

Parameters:

searcher - the user performing the search which will be used to provide context for the search.

query - contains the information required to perform the search.

pager - Pager filter (use PagerFilter.getUnlimitedFilter() to get all issues).

Returns:

A SearchResults containing the resulting issues.

Throws:

SearchException - thrown if there is a severe problem encountered with lucene when searching (wraps an IOException).

ClauseTooComplexSearchException - if the query or part of the query produces lucene that is too complex to be processed.

searchCount

public long searchCount(ApplicationUser searcher,
                        Query query)
                 throws SearchException

Description copied from interface: SearchService

Search the index, and return the count of the issues matching the query.

Specified by:

searchCount in interface SearchService

Parameters:

searcher - the user performing the search, which will be used to create a permission filter that filters out any of the results the user is not able to see and will be used to provide context for the search.

query - contains the information required to perform the search.

Returns:

the number of issues matching the query

Throws:

SearchException - thrown if there is a severe problem encountered with lucene when searching (wraps an IOException).

searchCountOverrideSecurity

public long searchCountOverrideSecurity(ApplicationUser searcher,
                                        Query query)
                                 throws SearchException

Description copied from interface: SearchService

Return the number of issues matching the provided search criteria, overridding any security constraints.

As the method name implies, it bypasses the security restrictions that would normally be applied when performing a search. As such, it should only be used for administrative tasks where you really need to know about ALL affected issues.

Note: Searching for the count avoids loading the issue data into memory, so this should be preferred when the count is all you need to know.

Specified by:

searchCountOverrideSecurity in interface SearchService

Parameters:

searcher - the user performing the search which will be used to provide context for the search.

query - contains the information required to perform the search.

Returns:

number of matching results.

Throws:

SearchException - thrown if there is a severe problem encountered with lucene when searching (wraps an IOException).

ClauseTooComplexSearchException - if the query or part of the query produces lucene that is too complex to be processed.

getSearchContext

public SearchContext getSearchContext(ApplicationUser searcher,
                                      Query query)

Description copied from interface: SearchService

This produces an old-style SearchContext based on the passed in search query and the user that is performing the search.

This will only make sense if the query returns true for SearchService.doesQueryFitFilterForm(ApplicationUser, Query) since SearchContext is only relevant for simple queries.

The more acurate context can be gotten by calling SearchService.getQueryContext(ApplicationUser, Query).

If the query will not fit in the simple issue navigator then the generated SearchContext will be empty. This method never returns a null SearchContext, even when passed a null SearchQuery.

Specified by:

getSearchContext in interface SearchService

Parameters:

searcher - the user performing the search, not always the SearchRequest's owner

query - the query for which you want a context

Returns:

a SearchContext with the correct project/issue types if the query fits in the issue navigator, otherwise an empty SearchContext. Never null.

getQueryString

public String getQueryString(ApplicationUser user,
                             Query query)

Description copied from interface: SearchService

Returns the query string to represent the specified SearchQuery.

The query string is prepended with "&jqlQuery=" so that it is ready for use in building a URL.

Specified by:

getQueryString in interface SearchService

Parameters:

user - the user performing the search

query - the SearchQuery to generate the query string of. Does not accept null.

Returns:

a String which represents the query string of a SearchQuery (ie no context/base applied). Never null.

getIssueSearchPath

public String getIssueSearchPath(ApplicationUser user,
                                 SearchService.IssueSearchParameters params)

Description copied from interface: SearchService

Returns the URL relative to the app context to represent the specified issue search.

The URL is composed by the issue search path and provided parameters (e.g. "&/issues/?jql=...&filter=..."), but does NOT include the context path.

Specified by:

getIssueSearchPath in interface SearchService

Parameters:

user - the user performing the search

params - the parameters to generate the URL. Possible parameters are filter Id and query (JQL), both are optional but you cannot use both at the same time. Does not accept null.

Returns:

a String which represents the issue search URL and query string corresponding to the parameters (no context/base applied). Never null.

parseQuery

public SearchService.ParseResult parseQuery(ApplicationUser searcher,
                                            String query)

Description copied from interface: SearchService

Parses the query string into a JQL Query.

Specified by:

Description copied from interface: SearchService

Gets the JQL string representation for the passed query. Returns the string from Query.getQueryString() if it exists or generates one if it does not. Equilavent to:

  if (query.getQueryString() != null)
    return query.getQueryString();
  else
    return getGeneratedJqlString(query);
 

Specified by:

getJqlString in interface SearchService

Parameters:

query - the query. Cannot be null.

Returns:

the JQL string represenation of the passed query.

getGeneratedJqlString

public String getGeneratedJqlString(Query query)

getGeneratedJqlString in interface SearchService

Parameters:

query - the query. Cannot be null.

Returns:

the generated JQL string representation of the passed query.

Description copied from interface: SearchService

Returns an equivalent Query with all the potential "information leaks" removed, with regards to the specified user. For example, if the query contains the clause "project = Invisible", and the specified user does not have browse permission for project "Invisible", the sanitised query will replace this clause with "project = 12345" (where 12345 is the id of the project).

Specified by:
