Text query
HI,
What are the lucene features supported by Ignite Text query ?
i see case insensitive term search is working and regex is not working.
Could you please point me the complete documentation of ignite text query
features ?
Thanks.

Hi,
To my knowledge there are no such limitations. Can you clarify why regex and
others do not work for you?

Hi Anil,
Unfortunatelly, lucene index creation is hardcoded in Ignite and there is
no workaround here.
However you, are free to create a Jira ticket and propose a solution.
It looks like we should add ability to provide Lucene configuration within
Ignite CacheConfiguration, but I wouldn't like to mix and have dependency
of foreign API.
Another way here is to implement your own IndexingSpi.

Got it. I believe there is no mechanism to inject custom analyzer. I'm not a
big Lucene expert, do you have an example of how this can be done?

The answer is no, there is currently no easy way to do this. The only thing
you can do is implement your own IndexingSpi, but this will require to
implement indexing and querying logic from scratch.
Why do you want to do this? Are there any issues you have with the text
queries in Ignite?

Re: Text query
Posted by Anil <an...@gmail.com>.
i see following
Supports –
1. Case insensitive term search (global and specific field)
2. Boolean queries
3. Wildcard search
Not supports –
1. Regex
2. Stemming
3. Synonyms
4. Highlight (obviously) - it makes no sense for ignite
Can we configure tokenizer and filters for query and index analyzers ?
Thanks for your help.
