David Smiley commented on SOLR-14597:
-------------------------------------

It's great to see you got the Lucene stuff in!
Judging from merely glancing at the files touched in your PR (I didn't look at 
the contents), it appears there are some Solr improvements that could be made; 
yes?  Could you separate them into other JIRA issues?  If any are trivial and 
not JIRA issue worthy than a PR is fine, in accordance with our development 
guidelines.

I'm "-0" on adding AQP to Solr.  It's a non-trivial bunch of code.  I'd rather 
it go to another repo (anywhere) and only have it come into our repo based on 
>= 3 users wanting it.  I was similarly conservative about the OpenSextant 
"Text Tagger" that only came in after I got enough feedback from enough people 
so that I felt I was not abusing my privileges in the project, thus incurring 
an undue long-term maintenance burden.

> This JIRA ticket tracks the progress of SIP-9, the Advanced Query Parser that 
> is being donated by the Library of Congress. Full description of the feature 
> can be found on the SIP Page.
> [https://cwiki.apache.org/confluence/display/SOLR/SIP-9+Advanced+Query+Parser]
> Briefly, this parser provides a comprehensive syntax for users that use 
> search on a daily basis. It also reserves a smaller set of punctuators than 
> other parsers. This facilitates easier handling of acronyms and punctuated 
> patterns with meaning ( such as C++ or 401(k) ). The new syntax opens up some 
> advanced features while also preventing access to arbitrary features via 
> local parameters. This parser will be safe for accepting user queries 
> directly with minimal pre-parsing, but for use cases beyond it's established 
> features alternate query paths (using other parsers) will need to be supplied.
> The code drop is being prepared and will be supplied as soon as we receive 
> guidance from the PMC regarding the proper process. Given that the Library 
> already has a signed CCLA we need to understand which of these (or other 
> processes) apply:

> and
