Description

I propose that ExtractingRequestHandler / SolrCell literals should take precedence over Tika-parsed metadata in all situations, including where multiValued="true". (Compare SOLR-1633?)

My personal motivation is that I have several fields (e.g. "title", "date") where my own metadata is much superior to what Tika offers, and I want to throw those Tika values away. (I actually wouldn't mind throwing away all Tika-parsed values, but let's set that aside.) SOLR-1634 is one potential approach to this, but the fix here might be simpler.

I'll attach a patch shortly.

• is broken by: SOLR-5375 Param "literalsOverride" for ExtractingRequestHandler / SolrCell does not consider "lowernames"
• is related to: SOLR-1803 ExtractingRequestHandler does not propagate multiple values to a multi-valued field
• relates to: SOLR-1633 Solr Cell should be smarter about literal and multiValued="false"
• relates to: SOLR-1634 change order of field operations in SolrCell
