Hi Erick,
Thanks for the response.
I understood the reason for the regex match not working.
The help that I am looking from this forum is as below.
1. All the example regex query are to match one term only, Is there a
way in Solr to match multiple term?
2. How can make a similar query in Solr? Sample Query will help
us instead of providing the Query parser name.
Lack of documentation on these feature is causing the confusion to me.
Thanks in advance for your help.
Regards,
Suresh.A

Right. As I mentioned on the original JIRA, the regex match is happening on
_terms_.
You are conflating the original input (the entire field) with the individual
terms that the regex is applied to.
I suggest that you look at the admin/analysis page. There you'll see the terms
that are indexed and you'll see that the regex simply cannot work since it
assumes that the regex is applied to the entire input rather than the results
of the analysis chain.
I further suggest that you explore tokenization and how individual terms are
searched. The admin/analysis page is invaluable in this endeavor.
The root cause of your confusion is that, given you're using ClassicTokenizer,
you have a bunch of individual terms that are being searched, _not_ the whole
input. So the regex is bound to fail since you're thinking in terms of the
entire input rather than the result of your analysis chain, i.e. tokenization +
filters as defined in schema.xml.
FWIW,
Erick
