Regexp in SphinxSE & Stopwords not working

Hello,
How to use Regexp() function in SphinxSE.
Also adding stopwords doesn’t affect any resultset.

Thanks in advance

What are you trying to do with Regexp() ? - its not really clear what you mean.

As for stopwords, again I think we need more detail to understand your issue. You might simply be misunderstanding how it work.

Hi,
Thanks for the reply & sorry for not making it clear. Hope the below example makes you understood & let me know if I misunderstood those functions.

  1. We have “Adventure” & “Advent” as keywords to match. If I give “Advent” in keyword search it only give results that met “Advent” but not “Adventure”. But after adding in wordforms it will met both results. So is there any functions to met & give both results without adding in wordforms.

  2. Ignore Stopwords - If we search “Bag of words” , then need to match “Bag words”.

  1. That sounds like morphology

  1. That sounds sound like what stopwords option does.
    Needs setup

If you are using morphology (or wordforms!) may need stopwords_unstemmed
