Advanced Search

[almasaeed2010]

This PR introduces a few things:

• Synonyms based off of WordNet
• Stop word "tolerance"
• Support for filtering by field in a new Advanced Search page

Missing:

• Instructions on where to place the synonyms file
• A checkbox to indicate whether we should apply the synonyms filter

This builds on the faceted-search branch so merge there

[almasaeed2010]

When the checkbox for including synonyms is checked we need to ask the user for the file path and the format of the file. Those values can default to ./synonyms/wn_s.pl and wordnet. We also need to specify that this index supports synonyms in the tripal_elasticsearch_indices table, which would require a migration to add a new column.

I am gonna start the indexing process on our dev server for the meeting tomorrow to see whether this functions well with large amounts of data.
