Hi,
Erik Hatcher a écrit :
No, this hasn't been done except for the basic Query.toString() output which for the most part is parsable again.
The question is, what do you do about the analysis process? It's a one-way transformation - and parsing again may not yield the same query.
We (the SDX developpers) have had quite the same need, i.e. to make a QueryParsed String parsable again, more often than most of the cases :-)
In fact, we did half of the job ; I mean... prevent analysis :-)
Look at http://savannah.nongnu.org/cgi-bin/viewcvs/sdx/sdx_v2/src/java/fr/gouv/culture/sdx/search/lucene/queryparser/DefaultQueryParser.jj?rev=1.16&content-type=text/vnd.viewcvs-markup
and search for : NO_ANALYSIS
You will see that we need an "UnanalyzedQuery" class which is already packaged for Lucene ;-)
http://savannah.nongnu.org/cgi-bin/viewcvs/sdx/sdx_v2/src/java/org/apache/lucene/search/UnanalyzedQuery.java?rev=1.4&content-type=text/vnd.viewcvs-markup
The other half could be done by a method like OriginalQuery(String field) that would return this kind of string representation :
field:re_analyze_me (i.e. the original token)
or, the SDX way, modify the existing Query(String field) so that it would return this kind of string representation :
field:|alreay_analyzed_no_need_to_reanalyze_me|
What do you think ?
Cheers,
p.b.
