Erik Hatcher commented on SOLR-1895:
------------------------------------
bq. I don't think PostFilter has anything to do with this issue – IIUC, Post
filter is a good way to filter results after the query one-by-one. This
component adds a Query to the list of filters in the prepare stage. It works in
tandem with an indexing strategy that puts corresponding tokens on documents.
I guess you're right, as that'd be an implementation detail that would create
any post filtering queries using a PostFilter implementation, and then adding
wrapping with a QueryWrapperFilter... but probably MCF's filtering would
benefit from post filtering too since it may not be advantageous/desirable to
cache those filters. (maybe they aren't being cached given how they are
created now anyway)
bq. I just realized that Erik's proposal is somewhat different and seems to
involve a broader integration. If that's what winds up being done I'd like a
pointer to an existing example so I can stay consistent.
Yeah, basically like picking a spell check implementation or any of the other
subplugins we have within the various SearchComponent's in Solr.
As for my involvement here - I've got no time in the near future to contribute
an implementation of my idea, but should be fairly straightforward to leverage
the ideas of how other Solr SearchComponents get their implementation details
via named "plugins".

> I've written an LCF SearchComponent which filters returned results based on
> access tokens provided by LCF's authority service. The component requires
> you to configure the appropriate authority service URL base, e.g.:
> <!-- LCF document security enforcement component -->
> <searchComponent name="lcfSecurity" class="LCFSecurityFilter">
> <str
> name="AuthorityServiceBaseURL">http://localhost:8080/lcf-authority-service</str>
> </searchComponent>
> Also required are the following schema.xml additions:
> <!-- Security fields -->
> <field name="allow_token_document" type="string" indexed="true"
> stored="false" multiValued="true"/>
> <field name="deny_token_document" type="string" indexed="true"
> stored="false" multiValued="true"/>
> <field name="allow_token_share" type="string" indexed="true"
> stored="false" multiValued="true"/>
> <field name="deny_token_share" type="string" indexed="true" stored="false"
> multiValued="true"/>
> Finally, to tie it into the standard request handler, it seems to need to run
> last:
> <requestHandler name="standard" class="solr.SearchHandler" default="true">
> <arr name="last-components">
> <str>lcfSecurity</str>
> </arr>
> ...
> I have not set a package for this code. Nor have I been able to get it
> reviewed by someone as conversant with Solr as I would prefer. It is my
> hope, however, that this module will become part of the standard Solr 1.5
> suite of search components, since that would tie it in with LCF nicely.
