> 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:
