------------------------------------
Summary: Use LuceneQuery parser to create query from fulltext
string
Key: OAK-2329
URL: https://issues.apache.org/jira/browse/OAK-2329
Project: Jackrabbit Oak
Issue Type: Sub-task
Components: oak-lucene
Reporter: Chetan Mehrotra
Assignee: Chetan Mehrotra
Fix For: 1.2
Currently the Oak QueryEngine parses the fulltext expression and
produces the FulltextExpression. This was required for runtime
aggregation to work. This allowe [d the LuceneIndex to just convert
the given text (in FulltextTerm) to corresponding Lucene Query [1].
Note that JCR contract for fulltext clause [2] supports some grammer
which was so far handled by the Oak QueryEngine.
Now when moving to index time aggregation it was realized that such parsing of
fulltext expression is problamatic [3] in presence of
different analyzers. As we fix that we need also support the
requirements mentioned in [2]. JR2 used to do that via Lucene
QueryParser [4].
As a fix {{LucenePropertyIndex}} should use a Lucene QueryParser to construct
the query.
Now need to determine which parser to use [5] :).
[SimpleQueryParser|https://issues.apache.org/jira/browse/LUCENE-5336] looks
useful!
