Method Detail

search

java.util.List search(org.apache.lucene.search.Query query)

Performs the search operation and returns a List of found items.

search

java.util.List search(org.apache.lucene.search.Query myquery,
                      org.apache.lucene.search.Sort sort)

buildStandardQuery

org.apache.lucene.search.Query buildStandardQuery(java.lang.String[] searchFields,
                                                  java.lang.String query)

Performs a search over multiple fields

Parameters:

searchFields - a sting array of fields to search accross

query - the qury to execute

Returns:

a list of Hit results

buildStandardQuery

org.apache.lucene.search.Query buildStandardQuery(java.lang.String field,
                                                  java.lang.String query)

searchForFields

java.util.List searchForFields(org.apache.lucene.search.Query myquery,
                               java.util.Set fieldsToExtract,
                               int startIndex,
                               int numItems)

Search an index and return not only the item handles, but also pull arbitrary fields from the document and return them too.

Extracting fields from all documents could be expensive and potentially unnecessary, so the startIndex and numItems parameters allow you to control where the extraction will start from, and how many items it will continue for.

Parameters:

myquery - The query to run

fieldsToExtract - A set of field names which will be extracted from the document and returned - if the fields are null, or the set is empty, BaseDocumentBuilder.FieldName.HANDLE_FIELD_NAME will be used.

startIndex - The index to start extracting content from, or 0 for the start of the list

numItems - The number of items to be extracted in total, or Integer.MAX_VALUE for all items

Returns:

A list containing maps of the fields you wish to extract. For results outside of the startIndex/numItems range, this list will contain null values.
