Interface SearchProvider

All Known Implementing Classes:
LuceneSearchProvider

public interface SearchProvider

A SearchProvider in JIRA allows users to run structured searches against JIRA Lucene index as opposed to database (SQL) based queries. All search methods take a Query which defines the criteria of the search, including any sort information.

Method Detail

search

SearchResults search(Query query,
                     com.opensymphony.user.User searcher,
                     PagerFilter pager)
                     throws SearchException
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. Also note that if you are only after the number of search results use searchCount(com.atlassian.query.Query ,com.opensymphony.user.User) as it provides better performance.

Parameters:
query - contains the information required to perform the search.
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.
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.

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.
pager - Pager filter (use PagerFilter.getUnlimitedFilter() to get all issues).
andQuery - raw lucene Query to AND with the request.
Returns:
A SearchResults containing the resulting issues.
Throws:

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. Do not use this method, user search(com.atlassian.query.Query , com.opensymphony.user.User, com.atlassian.jira.web.bean.PagerFilter, org.apache.lucene.search.Query) instead, this should only be used when performing administrative tasks where you need to know ALL the issues that will be affected. 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 searchCount(com.atlassian.query.Query ,com.opensymphony.user.User) as it provides better performance.

Parameters:
query - contains the information required to perform the search.
searcher - the user performing the search which will be used to provide context for the search.

                                 throws SearchException
Return the number of issues matching the provided search criteria, overridding any security constraints. Do not use this method, use searchCount(com.atlassian.query.Query , com.opensymphony.user.User) instead, this should only be used when performing administrative tasks where you need to know ALL the issues that will be affected. Note: This does not load all results into memory and provides better performance than search(com.atlassian.query.Query ,com.opensymphony.user.User,com.atlassian.jira.web.bean.PagerFilter)

search

void search(Query query,
            com.opensymphony.user.User searcher,
            org.apache.lucene.search.HitCollector hitCollector)
            throws SearchException
Run a search based on the provided search criteria and, for each match, call hitCollector.collect(). HitCollectors are low level Lucene classes, but they allow issues to be placed into buckets very quickly. Many of JIRA's graphs and stats are generated in this manner. This method is useful if you need to execute a query in constant-memory (i.e. you do not want to load the results of your complete search into memory).

Parameters:
query - contains the information required to perform the search.
searcher - the user performing the search which will be used to provide context for the search.
hitCollector - the Lucene object that will have collect called for each match.
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.

            throws SearchException
Run a search based on the provided search criteria and, for each match, call hitCollector.collect(). HitCollectors are low level Lucene classes, but they allow issues to be placed into buckets very quickly. Many of JIRA's graphs and stats are generated in this manner. This method is useful if you need to execute a query in constant-memory (i.e. you do not want to load the results of your complete search into memory) and the query generated via JQL needs to be augmented with some custom Lucene query.

Parameters:
query - contains the information required to perform the search.
searcher - the user performing the search which will be used to provide context for the search.
hitCollector - the Lucene object that will have collect called for each match.
andQuery - additional Lucene query to be anded with the lucene query that will be generated from JQL
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.

searchOverrideSecurity

This method is useful if you need to execute a query in constant-memory (i.e. you do not want to load the results of your complete search into memory).

Parameters:
query - contains the information required to perform the search.
searcher - the user performing the search which will be used to provide context for the search.
hitCollector - the Lucene object that will have collect called for each match.
Throws:
SearchException - thrown if there is a severe problem encountered with lucene when searching (wraps an IOException).

You may limit the number of results being collected by the HitCollector using the PagerFilter parameter. This method is useful if you need to execute a query in constant-memory (i.e. you do not want to load the results of your complete search into memory).

Parameters:
query - contains the information required to perform the search.
searcher - the user performing the search which will be used to provide context for the search.
