QueryParser.setAutoGeneratePhraseQueries()

Elastic Stack Elasticsearch
1

Hi,

I wonder if QueryParser.setAutoGeneratePhraseQueries() is exposed through
API.
From Lucene 3.1, the default value of AutoGeneratePhraseQueries becomes
"false" for some reason. It breaks CJK queries. To make CJK queries to work,
we need to call QueryParser.setAutoGeneratePhraseQueries(true).

If it's not possible, can I open a ticket for it?

Thanks,
Iori

I think setting this to "true" breaks CJK queries... eg see
http://markmail.org/thread/ww6mhfi3rfpngmc5

It was changed to "false" by default in Lucene (see
[LUCENE-2458] queryparser makes all CJK queries phrase queries regardless of analyzer - ASF JIRA ) to not break CJK
queries.

But I agree this setting should be controllable via ES.

Hi,

"break" might not be right word. It is "break" for us, though.
It doesn't return the same result as previous version and we need
QueryParser to behave the same as 3.0.

Anyway, I will create a ticket.

Yea, this field is not exposed in ES, open an issue, easy to expose.

Ahh, OK, makes sense.

You (or ES) could also pass Version.LUCENE_30 as the "matchVersion"
param to QueryParser.

Hi,

Yes, actually I ended up re-setting org.elasticsearch.common.lucene.Lucene.QUERYPARSER_VERSION using reflection.
But it looks I don't need it any more since this is already implemented :slight_smile:
