6+Elasticsearch client and query DSL for Haskell
7+==============================================
8+
9+Why?
10+----
11+
12+Search doesn't have to be hard. Let the dog do it.
13+
14+Endorsements
15+------------
16+
17+"Bloodhound makes Elasticsearch almost tolerable!" - Almost-gruntled user
18+
19+"ES is a nightmare but Bloodhound at least makes it tolerable." - Same user, later opinion.
20+
21+Version compatibility
22+---------------------
23+
24+As of version 0.13.0.0, Bloodhound has 2 separate module trees for
25+Elasticsearch versions 1 and 5. Import the module that is appropriate
26+for your use case. If you would like to add support for another major
27+version, open a ticket expressing your intend and follow the pattern
28+used for other versions. We weighed the idea of sharing code between
29+versions but it just got too messy, especially considering the
30+instability of the Elasticsearch API. We switched to a model which
31+would allow the persons responsible for a particular protocol version
32+to maintain that version while avoiding conflict with other versions.
33+
34+See our [TravisCI](https://travis-ci.org/bitemyapp/bloodhound) for a
35+listing of Elasticsearch version we test against.
36+
37+
38+Stability
39+---------
40+
41+Bloodhound is stable for production use. I will strive to avoid breaking API compatibility from here on forward, but dramatic features like a type-safe, fully integrated mapping API may require breaking things in the future.
42+
43+Testing
44+---------
45+
46+The TravisCI tests are run using [Stack](http://docs.haskellstack.org/en/stable/README.html). You should use Stack instead of `cabal` to build and test Bloodhound to avoid compatibility problems. You will also need to have an Elasticsearch instance running at `localhost:9200` in order to execute some of the tests. See the "Version compatibility" section above for a list of Elasticsearch versions that are officially validated against in TravisCI.
47+
48+Steps to run the tests locally:
49+ 1. Dig through the [past releases] (https://www.elastic.co/downloads/past-releases) section of the Elasticsearch download page and install the desired Elasticsearch versions.
50+ 2. Install [Stack] (http://docs.haskellstack.org/en/stable/README.html#how-to-install)
51+ 3. In your local Bloodhound directory, run `stack setup && stack build`
52+ 4. Start the desired version of Elasticsearch at `localhost:9200`, which should be the default.
53+ 5. Run `stack test` in your local Bloodhound directory.
54+ 6. The unit tests will pass if you re-execute `stack test`. If you want to start with a clean slate, stop your Elasticsearch instance, delete the `data/` folder in the Elasticsearch installation, restart Elasticsearch, and re-run `stack test`.

18−Bloodhound is alpha at the moment. The library works fine, but I don't want to mislead anyone into thinking the API is final or stable. I wouldn't call the library "complete" or representative of everything you can do in Elasticsearch but compared to clients in other languages, the usability is good.

152+* @bitemyapp
153+ - Add http-client-0.5.0 support
154+
155+0.11.0.0
156+===================
157+
158+Thanks to the following people, Bloodhound 0.10.0.0 is being released! This one gets a bit messy due to the Aeson 0.11 changeover, but this should be good to go now. Note that Aeson 0.11 returned to Aeson 0.9's behavior and semantics.

161+ - #112 List indices support
162+ - #94 Implement index optimization
163+ - #91 Make `respIsTwoHunna` more semantic
164+ - More detail: This is actually the cause of a bug in real code. If you happen to be
165+ using parseEsResponse (which uses respIsTwoHunna) to parse the result of
166+ certain operations such as creating an index, those operations return a
167+ 201 and unjustly are deemed to be a failure.
168+ - Cleaned up errant Haskell tokens in README
169+ - #84 Added request auth hooks
170+

179+ - Removed unused server versions from the tests
180+ - Updated readme to reflect actual ES versions supported and tested
181+ - Added support for parsing results of Missing Aggregations
182+ - #104 Export BucketValue
183+ - #102 Add local testing instructions to the README
184+ - #89 Support Bool and Numeric keys in TermsResults
185+ - Added Missing Aggregation support
186+ - #98 Improve EsProtocolException documentation for human error
187+ - Updated README to warn about 2.0 compatibility
188+ - Fix docs specifying an incorrect terminating condition
189+
190+* @bitemyapp
191+ - Merge monkey, puzzled over spurious local doctest failures
192+
193+0.10.0.0
194+===================
195+
196+Thanks to the following people, Bloodhound 0.10.0.0 is being released! This one gets a bit messy due to the Aeson 0.10 upgrade, so you may want to wait for the dust to settle. YMMV.
197+
198+* @MichaelXavier
199+ - #77: Add test for error parsing
200+ - #76/#78: Support for updating (modifying) index settings

204+
205+* @bitemyapp
206+ - Fucked around with dependencies and broke things in order to upgrade to Aeson 0.10
207+ - Please forgive me.
208+

211+

220+
221+* @centromere
222+ - #72 Added parent support to documentExists
223+
224+
225+0.8.0.0
226+===================
227+
228+Thanks to the following people, Bloodhound 0.8.0.0 is being released!

19+-- Data types for describing actions and data structures performed to interact
20+-- with Elasticsearch. The two main buckets your queries against Elasticsearch
21+-- will fall into are 'Query's and 'Filter's. 'Filter's are more like
22+-- traditional database constraints and often have preferable performance
23+-- properties. 'Query's support human-written textual queries, such as fuzzy
24+-- queries.
