[ckan-dev] Dataset Search

[Mike Sinclair]

I looked into solr and found a way to match partial strings without
breaking anything. You just need to add:

    <fieldType name="text" class="solr.TextField"
positionIncrementGap="100">
        <analyzer type="index">
            <tokenizer class="solr.WhitespaceTokenizerFactory"/>
            <filter class="solr.WordDelimiterFilterFactory"
generateWordParts="1" generateNumberParts="1" catenateWords="1"
catenateNumbers="1" catenateAll="0" splitOnCaseChange="1"/>
            <filter class="solr.LowerCaseFilterFactory"/>
            <filter class="solr.SnowballPorterFilterFactory"
language="English" protected="protwords.txt"/>
            <filter class="solr.ASCIIFoldingFilterFactory"/>
            *<filter class="solr.EdgeNGramFilterFactory" minGramSize="3"
maxGramSize="15"/>*
        </analyzer>

Storing groups and orgs in solr makes sense to me. Right now it seems sort
of disjointed.
