Evaluate different ElasticSearch features

[antonisloizou]

So this about things like stemming , synonyms, misspellings..
I guess many of these are nice to have, but the more we allow "non-exact" matches , the more false positives we might introduce in the results.

So we'll need to experiment to find a good balance

Misspellings can be done using 'fuzziness' eg. Asprin would (in the current index) list Aspirin as the second hit using the default 'AUTO' setting for fuzzines. See https://www.elastic.co/guide/en/elasticsearch/guide/current/fuzzy-query.html for more details.

[ianwdunlop]

Setting the fuzziness to '1' makes Aspirin the top hit for Asprin.

Is there a list of life sciences/pharamceutical/chemistry synonyms?

[nicklynch]

Suppose there are different options:
For alternate drug names: Drugbank
For general chemistry names:
Did ConceptWiki store that? Could we ask them?
There is type of free service but its not the full data set, just an API http://www.commonchemistry.org/

Not sure about common typos

[ianwdunlop]

For stemming we need to index a different field at load time which contains the stemmed version and then include it in the searched fields via the API.
