Recoll_ is a desktop full-text search tool based on Xapian. By itself Recoll_
|
|
does not offer WEB or API access, this can be achieved using recoll-webui_
|
|
|
|
Configuration
|
|
=============
|
|
|
|
You must configure the following settings:
|
|
|
|
``base_url``:
|
|
Location where recoll-webui can be reached.
|
|
|
|
``mount_prefix``:
|
|
Location where the file hierarchy is mounted on your *local* filesystem.
|
|
|
|
``dl_prefix``:
|
|
Location where the file hierarchy as indexed by recoll can be reached.
|
|
|
|
``search_dir``:
|
|
Part of the indexed file hierarchy to be search, if empty the full domain is
|
|
searched.
|
|
|
|
Example
|
|
=======
|
|
|
|
Scenario:
|
|
|
|
#. Recoll indexes a local filesystem mounted in ``/export/documents/reference``,
|
|
#. the Recoll search interface can be reached at https://recoll.example.org/ and
|
|
#. the contents of this filesystem can be reached though https://download.example.org/reference
|
|
|
|
.. code:: yaml
|
|
|
|
base_url: https://recoll.example.org/
|
|
mount_prefix: /export/documents
|
|
dl_prefix: https://download.example.org
|
|
search_dir: ''
