New is now used to create new indexes
Open is used to open existing indexes
calls to Open no longer specify a mapping because the mapping
is serialized and stored along with the index
ultimately this is make it more convenient for us to wire up
different elements of the analysis pipeline, without having to
preload everything into memory before we need it
separately the index layer now has a mechanism for storing
internal key/value pairs. this is expected to be used to
store the mapping, and possibly other pieces of data by the
top layer, but not exposed to the user at the top.
this change was then exposed at the higher levels
also the beer-sample app was upgraded to index in batches of 100
by default. this yieled an indexing speed up from 27s to 16s.
closes#57
introduced concept of byte array converters
right now only wired up to top-level index mapping
allowing the removal of the JSON methods, now at the top level
we default to parsing []byte as JSON, override if thats not
the behavior you want.
future enhancements will allow use of these byte array converters
to control how byte arrays are handled elsewhere in documents
this would allow for handing binary attachments, etc in the future
closes#59
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)
new top level index api, closes#5
refactored index tests to not rely directly on analyzers
moved query objects to top-level
new top level search api, closes#12
top score collector allows skipping results
index mapping supports _all by default, closes#3 and closes#6
index mapping supports disabled sections, closes#7
new http sub package with reusable http.Handler's, closes#22
