Update synonym list from CourtListener

[mlissner]

This is a big addition to our synonym list. The source for this data is mostly from the Indigo Book, which has many tables of abbreviations, such as:

• U.S. States and Other Jurisdictions
• Services & Publishers
• Legislative Documents
• Treaties
• Arbitral Reporters
• Intergovernmental Organizations
• Court names
• Titles of judges and other people
• Case name abbreviations
• Geographical terms
• Document subdivistions (pargaph, section, etc)
• Explanatory phrases
• Institutions
• Publishing terms
• Month names
• Common words in periodical names

On top of that, I added a few things:

• Numbers from 1-20
• Units
• And any extra things I saw missing (like trans didn't have a mapping to transgender)

From there I did the following:

• Remove duplicates (of which there were many)

• Removed phrases (Solr is bad at this)

• Removed anything with a period or apostrophe in the middle, like, U.S., because those things get split by Solr anyway.

• Cleaned up a bunch of items that had brackets, like trans[lator, lation], trans. In the case that the expanded word lists were semantically different, I made them into mappings. Else, I made them into synonyms. For example, here's what trans maps to:

  trans => translation,translator,transgender
  

  This means that when you type trans the system doesn't know if you mean translator or transgender. OTOH, something else might just be:

  assemb,assembly,assemblyman,assemblywoman,assemblymember
  

  Because they're all essentially the same semantically.

• Eliminated one-letter abbreviations (they're not likely to be useful)

• Removed real words that'd cause trouble. For example, we wouldn't want every search for cat to turn up results for category.

All in all, I think she's a fine list. Definitely a conservative one, which lawyers like, but also one that should make lots of searches (especially those involving abbreviations) work better.
