Elastic Search Query Notes

Elastic search is quite powerful, and there are a few nice search features we can take advantage of:

1. Wildcard and regex queries work: http://www.elastic.co/guide/en/elasticsearch/guide/current/_wildcard_and_regexp_queries.html
2. Prefix searching for fast autocomplete: http://www.elastic.co/guide/en/elasticsearch/guide/current/_query_time_search_as_you_type.html

Note the full listing of query types can be found here

Indexing might help us, too, if the default inverted indices are not enough. The inverted index allows for regex, wildcard, and even edit-distance searching. However, other methods of indexing exist:

1. N-grams: http://www.elastic.co/guide/en/elasticsearch/guide/current/ngrams-compound-words.html
