Start of search research docs

The plan is to better understand how OS works so I can craft better
queries so I can have a better search functionality.

+# Partner Search Notes
+
+Very much a **WORK IN PROGRESS**.
+
+This is getting fairly complex with a lot of "in air" ideas that I'd like to get down before cleaning up all the hacky code I have written.
+
+Elastic Search and OpenSearch are the same thing. They can be run locally in a docker container (see `/docker/search`) but in production they are normally a service you connect to (by HTTPS). Written in Java.
+
+The way these things work is they ingest all your data into indices and then you query them and get back all that data - so synchronising your DB with your index is a chore that must be done.
+
+Searchkick is a gem that wraps OS and ES and makes them slightly less cumbersome but more Rails specific.

+
+## Operation
+
+There are two parts to search: ingesting and search.
+
+### Ingesting data
+
+### Search
+
+Very complicated (powerful) API that boils down to:
+
+```ruby
+  partners = Partner.search(name_value, <options>)
+  # the SearchKick way
+```
+
+Where options is a DSL.
+
+#### Finding documents by string
+
+```
+(but in `bool` field?)
+
+  multi-match
+    "analyzer": "searchkick_search"
+    "analyzer": "searchkick_search2"
+
+  (with)
+    boost set to 10 and 1
+    "fuzziness": not set and 1
+    "fuzzy_transpositions": true,
+    "prefix_length": 0,
+    "max_expansions": 3,
+
+```

+#### Filtering documents
+
+#### Ordering output
