[Proposal] solr query-builder

[floriansemm]

Related issue #420

QueryBuilder allows to define queries programmatically.

$builder
    ->select('title', 'content')
    ->where('id')
        ->equals('id_prefix_*')
    ->andWhere('title_s')
        ->equals('a title')
    ->orWhere('tags_ss')
        ->inSet(array('solr', 'symfony'));

A condition starts always with where / andWhere / orWhere, followed by equals($value)/ inSet($values)/ inRange($start, $end)/ inDistance($lat, $long, $distance).

I have also implemented a test-class to show the usage.

The implementation and featureset is very basic and should only start a discussion.

Interesting, but it is a big step backwards (features-wise) compared to #420, which has not even been merged neither. Probably it would be better to focalize the efforts into one single lib.

I think it's clear there is demand for a query builder, and I can also see the benefits myself.

As already discussed in #420 I think something like this could be a separate library, as it's very useful even without Solarium.
Since it is related to Solarium, we could create a project under the 'solariumphp' github organization.

@basdenooijer merge, solariumphp/builder, community lib, composer suggestion of my lib, .... the important thing is to do.... something :)

[basdenooijer]

I don't want to force any of the options. But the way I see it:

• The community lib option is always open to anyone.
• I'm also willing to merge a PR that adds such a lib to the composer suggestions
• If someone wants to take ownership of solariumphp/builder (or whatever name) I'm open for that.

Currently I don't have the time to take the lead in such a project, but if someone wants to do that (or even better, several people?) please let me know.
