aa439c1ea6 Fix long queries causing highlighter to misbehave and sometimes crash. 
A window of size 10 is used by the highlighter to mark overlap with query text. When query length exceeded 10 tokens, this caused the highlighter to break.

e1db28a153 When a facet field is filtered upon, search should be verbatim instead of normalizing the filter_by value. 
There was also a difference in the behavior between string and string array facet fields which is corrected in this PR.

c5b7f3c7e2 Return snippets of best matched array elements instead of just the best matched element.

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.

a2ce56fd67 Allow string fields to be filtered on.

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.
