Allow Apache Solr to be the default, let search module index 0 nodes per cron run

I think we have an issue for this already, but I don't see it.

@pwolanin: Do you know where it is?

And yes, I agree to the above points BUT it would be nice to have a *better* search framework so that users can seamlessly switch between Solr and Sphinx or back to core search without theming, etc issues.

So seeing as we don't have a better one, I'm a little reticent to move off of core search. I'm actually fine with it, but I think we should make sure we maintain compatibility.

hmm, I can't find it either.

Issues for Core searches
http://drupal.org/project/issues/coresearches

@coupet - no, this would be an issue for just this module.

It would be great if we could come up with the different scenarios for/against dependancy on core search. here's a possible starting list:

Cases when removal of core search dependancy is good:
* Don't need core search, and will no longer have core search indexing what is already on the Solr index.
* ??

Cases when it's bad:
* D7 or later gets the Search API it deserves, and Apache Solr module would have to "go back" and integrate with that.
* Would have to duplicate functionality offered in other modules (like OpenSearch which can now provide RSS for Apache Solr results).
* ??

Would it be too far-fetched to support two interfaces, one that would stand by itself, and another based on hook_search(), by refactoring some stuff into separate modules?

@David - that was basically my intention, since the amount of code specific to hook search is actually minimal.

With #469642: Pull facet blocks out of apachesolr_search.module (use facet_api), we could have a small step done to take some code out of apachesolr_search.module, to favor its re-use by other modules such as a potential search module that would not be dependent on core search.

Looking at this now - a little trickier than I initially thought since we use user_access('search content') and there is various block and theme code.

WIP, non-functional.

Thinking about htis more - it would be easier to just form_alter to allow 0 nodes indexed by core node search (thanks Jody).

new title, patch.

Committed...

Accidentally let CVS but the wrong comment in with -m on the command line once, but got it in proper.

Thank you for this, I was really confused why core Search needed to be used given the entire engine was being replaced. I will give the next beta a good solid thrashing on a 70k+ node site.
