Full-text Search
----------------

docs: add elasticsearch docs
r153 By default |RC| is configured to use `Whoosh`_ to index |repos| and
provide full-text search.
|RCE| also provides support for `Elasticsearch`_ as a backend for scalable
search. See :ref:`enable-elasticsearch` for details.
Indexing
^^^^^^^^
project: added all source files and assets
r1 To run the indexer you need to use an |authtoken| with admin rights to all
|repos|.
To index new content added, you have the option to set the indexer up in a
number of ways, for example:
* Call the indexer via a cron job. We recommend running this nightly,
unless you need everything indexed immediately.
* Set the indexer to infinitely loop and reindex as soon as it has run its
cycle.
* Hook the indexer up with your CI server to reindex after each push.
The indexer works by indexing new commits added since the last run. If you
wish to build a brand new index from scratch each time,
use the ``force`` option in the configuration file.
.. important::
You need to have |RCT| installed, see :ref:`install-tools`. Since |RCE|
3.5.0 they are installed by default.
To set up indexing, use the following steps:
1. :ref:`config-rhoderc`, if running tools remotely.
2. :ref:`run-index`
3. :ref:`set-index`
4. :ref:`advanced-indexing`
.. _config-rhoderc:
Configure the ``.rhoderc`` File
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
|RCT| uses the :file:`/home/{user}/.rhoderc` file for connection details
to |RCM| instances. If this file is not automatically created,
you can configure it using the following example. You need to configure the
details for each instance you want to index.
.. code-block:: bash
# Check the instance details
# of the instance you want to index
$ rccontrol status
- NAME: enterprise-1
- STATUS: RUNNING
- TYPE: Momentum
- VERSION: 1.5.0
- URL: http://127.0.0.1:10000
To get your API Token, on the |RCM| interface go to
:menuselection:`username --> My Account --> Auth tokens`
.. code-block:: ini
# Configure .rhoderc with matching details
# This allows the indexer to connect to the instance
[instance:enterprise-1]
api_host = http://127.0.0.1:10000
api_key = <auth token goes here>
repo_dir = /home/<username>/repos
.. _run-index:
Run the Indexer
^^^^^^^^^^^^^^^
Run the indexer using the following command, and specify the instance you
want to index:
.. code-block:: bash
# From inside a virtualevv
(venv)$ rhodecode-index --instance-name=enterprise-1
# Using default installation
$ /home/user/.rccontrol/enterprise-4/profile/bin/rhodecode-index \
--instance-name=enterprise-4
# Using a custom mapping file
$ /home/user/.rccontrol/enterprise-4/profile/bin/rhodecode-index \
--instance-name=enterprise-4 \
--mapping=/home/user/.rccontrol/enterprise-4/mapping.ini
.. note::
|RCT| require |PY| 2.7 to run.
.. _set-index:
Schedule the Indexer
^^^^^^^^^^^^^^^^^^^^
To schedule the indexer, configure the crontab file to run the indexer inside
your |RCT| virtualenv using the following steps.
1. Open the crontab file, using ``crontab -e``.
2. Add the indexer to the crontab, and schedule it to run as regularly as you
wish.
3. Save the file.
.. code-block:: bash
$ crontab -e
# The virtualenv can be called using its full path, so for example you can
# put this example into the crontab
# Run the indexer daily at 4am using the default mapping settings
* 4 * * * /home/ubuntu/.virtualenv/rhodecode-venv/bin/rhodecode-index \
--instance-name=enterprise-1
# Run the indexer every Sunday at 3am using default mapping
* 3 * * 0 /home/ubuntu/.virtualenv/rhodecode-venv/bin/rhodecode-index \
--instance-name=enterprise-1
# Run the indexer every 15 minutes
# using a specially configured mapping file
*/15 * * * * ~/.rccontrol/enterprise-4/profile/bin/rhodecode-index \
--instance-name=enterprise-4 \
--mapping=/home/user/.rccontrol/enterprise-4/mapping.ini
.. _advanced-indexing:
Advanced Indexing
^^^^^^^^^^^^^^^^^
|RCT| indexes based on the :file:`mapping.ini` file. To configure your index,
you can specify different options in this file. The default location is:
* :file:`/home/{user}/.rccontrol/{instance-id}/mapping.ini`, using default
|RCT|.
* :file:`~/venv/lib/python2.7/site-packages/rhodecode_tools/templates/mapping.ini`,
when using ``virtualenv``.
.. note::
If you need to create the :file:`mapping.ini` file, use the |RCT|
``rhodecode-index --create-mapping path/to/file`` API call. For details,
see the :ref:`tools-cli` section.
The indexer runs in a random order to prevent a failing |repo| from stopping
a build. To configure different indexing scenarios, set the following options
inside the :file:`mapping.ini` and specify the altered file using the
``--mapping`` option.
* ``index_files`` : Index the specified file types.
* ``skip_files`` : Do not index the specified file types.
* ``index_files_content`` : Index the content of the specified file types.
* ``skip_files_content`` : Do not index the content of the specified files.
* ``force`` : Create a fresh index on each run.
* ``max_filesize`` : Files larger than the set size will not be indexed.
* ``commit_parse_limit`` : Set the batch size when indexing commit messages.
Set to a lower number to lessen memory load.
* ``repo_limit`` : Set the maximum number or |repos| indexed per run.
* ``[INCLUDE]`` : Set |repos| you want indexed. This takes precedent over
``[EXCLUDE]``.
* ``[EXCLUDE]`` : Set |repos| you do not want indexed. Exclude can be used to
not index branches, forks, or log |repos|.
At the end of the file you can specify conditions for specific |repos| that
will override the default values. To configure your indexer,
use the following example :file:`mapping.ini` file.
.. code-block:: ini
[__DEFAULT__]
# default patterns for indexing files and content of files.
# Binary files are skipped by default.
# Index python and markdown files
index_files = *.py, *.md
# Do not index these file types
skip_files = *.svg, *.log, *.dump, *.txt
# Index both file types and their content
index_files_content = *.cpp, *.ini, *.py
# Index file names, but not file content
skip_files_content = *.svg,
# Force rebuilding an index from scratch. Each repository will be rebuild
# from scratch with a global flag. Use local flag to rebuild single repos
force = false
# Do not index files larger than 385KB
max_filesize = 385KB
# Limit commit indexing to 500 per batch
commit_parse_limit = 500
# Limit each index run to 25 repos
repo_limit = 25
# __INCLUDE__ is more important that __EXCLUDE__.
[__INCLUDE__]
# Include all repos with these names
docs/* = 1
lib/* = 1
[__EXCLUDE__]
# Do not include the following repo in index
dev-docs/* = 1
legacy-repos/* = 1
*-dev/* = 1
# Each repo that needs special indexing is a separate section below.
# In each section set the options to override the global configuration
# parameters above.
# If special settings are not configured, the global configuration values
# above are inherited. If no special repositories are
# defined here RhodeCode will use the API to ask for all repositories
# For this repo use different settings
[special-repo]
commit_parse_limit = 20,
skip_files = *.idea, *.xml,
# For another repo use different settings
[another-special-repo]
index_files = *,
max_filesize = 800MB
commit_parse_limit = 20000

Enabling Elasticsearch
^^^^^^^^^^^^^^^^^^^^^^
1. Open the :file:`rhodecode.ini` file for the instance you wish to edit. The
default location is
:file:`home/{user}/.rccontrol/{instance-id}/rhodecode.ini`
2. Find the search configuration section:
.. code-block:: ini
###################################
## SEARCH INDEXING CONFIGURATION ##
###################################
search.module = rhodecode.lib.index.whoosh
search.location = %(here)s/data/index
and change it to:
.. code-block:: ini
search.module = rc_elasticsearch
search.location = http://localhost:9200/
where ``search.location`` points to the elasticsearch server.
