c5b7f3c7e2 Return snippets of best matched array elements instead of just the best matched element. 
However, we limit the number of snippets returned to 5 for now.

0014e19ea6 Highlighting should include all search fields, and not just the best matched field. 2018-05-14 14:11:14 +05:30

2d7e75caa5 Support wildcard query: using a * would ignore the search query and consider all records for filter+sort. 2018-05-12 09:48:29 +05:30

56ed39e3ff Refactor topster to ensure that it handles insertion of duplicate keys. 
Instead of ignoring a duplicate blindly, ignore when match score is less than existing key.

d4d1a9e3bd Fuzzy prefix searching should rely on the intermediate cost rather than the final cost. 
Since we are only trying to match the prefix part, comparing the prefix with the full string makes no sense.

b669a47c29 Highlight best matched string in an array. 
An ARRAY_SEPARATOR delimiter is used to demarcate offsets of tokens from different indices of an array. Plain string fields are treated like a single-element array field, but without needing to use a delimiter.

c0d7e57c62 Only lowercase, don't substitute latin chars to ASCII. 
There was a noticeable slow-down. To be explored in future, potentially behind an optional flag.

b451a559e0 Improve error message logged when a replica is pointed to an old master. 
In such a case, the WAL entries would have expired - logging that explicitly now.

192b00e71f Address API review comments. 
1. Move document specific actions under /documents
2. Document creation echoes the full document
3. Collections summary returns full detail on each each collection
4. Collections summary endpoint has no nested root attribute
5. When collection or document is deleted, the whole entity is returned in response

c1c7d493e5 Allow an integer to be passed to a field defined as a float. 
In the real world, this is common and it's better to be practical here.

a2ce56fd67 Allow string fields to be filtered on. 
A rather convenient feature to have - but it would be a match of all tokens without typo tolerance.

0e4517d901 Combine search, facet and sort fields into a single "fields". 
1. All numerical fields are added to sort index automatically since that makes logical sense.
2. Search fields to be used as a facet are to have a `facet: true` property - removes duplication.
3. If someone wants to use a faceted field also to search against (rare scenario), then they can duplicate that field without the `facet: true` property.
