parsing of date ranges in queries no longer consults the
index mapping. it was deteremined that this wasn't very useful
and led to overly complicated query syntax/behavior.
instead, applications get set the datetime parser used for
date range queries with the top-level config QueryDateTimeParser
also, we now support querying date ranges in the query string,
the syntax is:
field:>"date"
>,>=,<,<= operators are supported
the date must be surrounded by quotes
and must parse in the configured date format
regexp, fuzzy and numeric range searchers now check to see if
they will be exceeding a configured DisjunctionMaxClauseCount
and stop work earlier, this does a better job of avoiding
situations which consume all available memory for an operation
they cannot complete
you can now use terms like:
test?string*
and similar text in query strings to perform wildcard
searches. also if you use:
/aregexp/
it will perform a regexp search as well
Currently bleve batch is build by user goroutine
Then read by bleve gourinte
This is still safe when used correctly
However, Reset() will modify the map, which is now a data race
This fix is to simply make batch.Reset() alloc new maps.
This provides a data-access pattern that can be used safely.
Also, this thread argues that creating a new map may be faster
than trying to reuse an existing one:

Separate but related, I have opted to remove the "unsafe batch"
checking that we did. This was always limited anyway, and now
users of Go 1.6 are just as likely to get a panic from the
runtime for concurrent map access anyway. So, the price paid
by us (additional mutex) is not worth it.
fixes#360 and #260
this change improves compatibility with the simple analyzer
defined by Lucene. this has important implications for
some perf tests as well as they often use the simple
analyzer.
this change only affects JSON parsing, any search request which
omits the size field entirely now defaults to 10 which
is the same behavior as NewSearchRequest()
0 is still a valid size, but must be set explicitly
several data structures had a pointer at the start of the struct
on some 32-bit systems, this causes the remaining fields no longer
be aligned on 64-bit boundaries
the fix identifed by @pmezard is to put the counters first in the
struct, which guarantees correct alignment
fixes#359
