Boostable, Fieldable, Validatable broken out into separate
interfaces. This allows them to be discoverable when
needed, but ignorable otherwise. The top-level bleve package
only every cares about Validatable and even that is optional.
Also, this change goes further to make the structure names
more reasonable, for cases where you're directly interacting
with the structures.
the index mapping contains some relatively messy logic
and the top-level bleve package only cares about a relatively
small portion of this
the motivation for this change is to codify the part that the
top-level bleve package cares about into an interface
then move all the details into its own package
NOTE: the top-level bleve package still has hard dependency on
the actual implementation (for now) because it must deserialize
mappings from JSON and simply assumes it is this one instance.
this is seen as OK for now, and this issue could be revisited
in a future change. moving the logic into a separate package
is seen as a simplification of top-level bleve, even though
we still depend on the one particular implementation.
The DumpXXX() methods were always documented as internal and
unsupported. However, now they are being removed from the
public top-level API. They are still available on the internal
IndexReader, which can be accessed using the Advanced() method.
The DocCount() and DumpXXX() methods on the internal index
have moved to the internal index reader, since they logically
operate on a snapshot of an index.
handlers now use varLookupFunc's to get variable values from
the request object. this allows applications to use whatever
mux/router they want, and extracting variables like
indexName and docID is up to the caller-provided function
closes#113
more things can return error now
in a couple of places we had to swallow errors because they didn't
fit the existing API. in these case and proactively in a few
others we now return error as well.
also the batch API has been updated to allow performing
set/delete internal within the batch
an IndexAlias allows you easily work with one logical Index
while changing the actual Index its pointing to behind the scenes
Changing which actual Index is backing an IndexAlias can be done
atomically so that your application smoothly transitions from
one Index to another.
A separate use of IndexAlias is allowed when the IndexAlias is
defined to point to multiple Indexes. In this case only the
Search() operation is supported, but the Search will be run
on each of the underlying indexes in parallel, and the results
will be merged.
removed analyzers (these are now built as needed through config)
removed html chacter filter (now built as needed through config)
added missing license header
changed constructor signature of filters that cannot return errors
filter constructors that can have errors, now have Must variant which panics
change cdl2 tokenizer into filter (should only see lower-case input)

top score collector allows skipping results
index mapping supports _all by default, closes#3 and closes#6
index mapping supports disabled sections, closes#7
