Re: Question for SynonymQuery

Right. SynonymMap.html#WORD_SEPARATOR was a redundant complication. Spaces work fine. On Thu, Jan 19, 2023 at 4:26 AM Anh Dũng Bùi wrote: > Thanks Mikhail! > > It turns out

Hello, Santam. It seems I achieved what you asking for. https://github.com/mkhludnev/likely/blob/381b491d25e4d2035dd5b8a891dfdcfe2b986b90/src/test/java/org/apache/lucene/playground/TestMultiPulty.java#L32 It expands API and UI into phrases, which match like you expect. On Fri, Jan 20, 2023 at 4:18

Re: Question for SynonymQuery

Thanks Mikhail! It turns out I used FlattenGraphFilter and cause the PositionLength to be all 1 and resulted in the behavior above =) A side note is that we don't need to use WORD_SEPARATOR in the synonym file. SynonymMap.Parser.analyze would tokenize and append the separator for us. Regards, An

Re: Question for SynonymQuery

r SynonymQuery; I have just used the standard QueryParser. Instead the synonym processing occurs in the indexing phase, which is not only simpler (one search pattern, one query), but also I think you would also find it gives you superior performance (because the synonym processing occurs once at indexing

Re: Question for SynonymQuery

Thanks everyone for the insight. I guess I'll use BooleanQuery then. There is also a caveat I noticed (not sure if it's an issue or not), which is slightly different from the mentioned thread. When I have a multi-word synonym, let say "wifi router" and "internet device". Then using SynonymGraphFil

Re: Question for SynonymQuery

Hello. 1)Yes. That's the purpose. 2) I've skimmed through QueryBuilder.java. Conclusion is that it creates BQ.SHOULD (however, there should be something like DisjunctionMaxQuery) over PhraseQuery or MultiPhraseQuery (-ies). Good hack! On Wed, Dec 28, 2022 at 2:23 AM Anh Dũng Bùi wrote: > Hi Luc
