API enhancements

[kyule]

Custom NEON additions to symbiota api:

• Occurrence search for NEON site and domain: can currently be done via dataset id but there is no place for users to see that HARV has dataset 3, for example. Locality is probably easier for a user to understand but it would need to allow for non-exact matches.
• Occurrence search by collection: Not ideal that it can only be done via the collid, the ability to do non-exact matches to the collection name would be helpful
• Occurrence search by eventDate2: Individuals may want to search by the end of the collection window -- lower priority but might confuse people since eventDate2 is the date in the sampleID when they are formatted with dates in them.
• Other identifiers: neon sampleID, sampleCode are potentially important

also, fyi "search" is spelled wrong under taxonomy/search in the explorer

I might add if I think of something else
