+When you create the application, set the callback

 ```

+Edit the Flask configuration `config_flask.py`

-- some github issues have no title
+- hashing and caching
-- github issues are just being re-indexed over and over
+    - <s>first, working out the logic of how we group items into sets
-- documents not showing up in results
+        - needs to be deleted

+        - needs to be added
+        - for docs, issues, and comments</s>
+    - second, when we add or update an item, need to:
+        - go through the motions, download file, extract text
+        - check for existing indexed doc with that id
+        - check if existing indexed doc has same hash
+            - if so, skip
+            - otherwise, delete and re-index
+
+Other bugs:
+- Some github issues have no title (?)
+- <s>Need to combine issues with comments</s>
+- Not able to index markdown files _in a repo_
+- (Longer term) update main index vs update diff index
+
+Needs:
+- <s>control panel</s>
+
+Thursday product:
+- Everything re-indexed nightly
+- Search engine built on all documents in Google Drive, all issues, markdown files
+- Using pandoc to extract Google Drive document contents
+- BRIEF quickstart documentation

+- Future plans to improve - plugins, improving matching
+- Subdomain plans
+- Folksonomy tagging and integration plans

+# Centillion Components
+
+Centillion keeps it simple.
+
+There are two components:
+
+* The `Search` object, which uses whoosh and various
+  APIs (Github, Google Drive) to build and manage
+  the search index. The `Search` object also runs all
+  queries against the search index. (See the
+  [Centillion Whoosh](centillion_whoosh.md) page
+  or the `centillion_search`.py` file
+  for details.)
+
+* Flask app, which uses Jinja templates to present the
+  user with a minimal web frontend that allows them
+  to interact with the search engine. (See the
+  [Centillion Flask](centillion_flask.md) page
+  or the `centillion`.py` file

+## What the flask server does
+
+Flask is a web server framework
+that allows developers to define
+behavior for specific endpoints,
+such as `/hello_world`, or
+<http://localhost:5000/hello_world>
+on a web server running locally.
+
+## Flask server routes
+
+- `/home`
+    - if not logged in, this redirects to a "log into github" landing page (not implemented yet)
+    - if logged in, this redirects to the search route
+
+- `/search`
+    - search template
+
+- `/main_index_update`
+    - update main index, all docs period
+
+- `/control_panel`
+    - this is the control panel, where you can trigger
+      the search index to be re-made

+# Centillion Whoosh
+
+The `centillion_search.py` file defines a
+`Search` class that serves as the backend
+for centillion.
+
+## What the Search class does
+
+The `Search` class has two roles:
+- create (and update) the search index
+    - this also requires the `Search` class
+      to define the schema for storing documents
+- run queries against the search index,
+  and package results up for Flask and Jinja
+
+## Search class functions
+
+The `Search` class defines several functions:
+
+- `open_index()` creates the schema
+
+- `add_issue()`, `add_md()`, `add_document()` have three diff method sigs and add diff types
+  of documents to the search index
+
+- `update_all_issues()` or `update_all_md()` or `update_all_documents()` iterates over items
+  and determines whether each item needs to be updated in the search index
+
+- `update_main_index()` - update the entire search index
+    - calls all three update_all methods
+
+- `create_search_results()` - package things up for jinja
+
+- `search()` - run the query, pass results to the jinja-packager

-See [plans.md](plans.md)
+To rebuild the search engine, visit the control panel route (`/control_panel`),
+for example at <http://localhost:5000/control_panel>.
+
+This allows you to rebuild the search engine index. The search index
+is stored in the `search_index/` directory, and that directory
+can be configured with centillion's configuration file.
+
+The diff search index is faster to build, as it only
