Full Text Search
Introduction
The search_elastic app integrates full text search into ownCloud, powered by Elasticsearch.
Prerequisites
There is only one pre-requisite for the search_elastic app, and that’s a fully functioning Elasticsearch server with the ingest-attachment processor to be present. The ingest-attachment processor lets Elasticsearch extract file attachments in common formats, such as PPT, XLS, and PDF.
To install the processor, from your Elasticsearch installation directory, run the following command:
bin/elasticsearch-plugin install ingest-attachment service elasticsearch restart
| Only Elasticsearch version 5.6 is fully supported. Versions 6 and 7 are yet to be supported. |
Install and Configure the search_elastic App
To install the search_elastic app:
-
Download and extract the tarball of the latest release of the search_elastic app to the apps directory (or custom apps directory) of your ownCloud instance.
-
Use the occ app:enable command to enable the search_elastic application.
-
Go to and set the hostname (or IP address) and port of the Elasticsearch server and click "Reset Index".
| The index can also be managed from the command-line, via the occ search:index commands. The commands let administrators create, rebuild, reset, and update the search index. |
Known Limitations
Currently, there are several known limitations to the app; these are:
-
Files are shown twice in search results when searching by filename.
-
If a shared file is renamed by the sharee (share receiver), the sharee cannot find the file using the new filename.
-
If the search query doesn’t match the start of at least one word in an available file’s name, no results are returned.
-
Search results are not updated when a text file is rolled back to an earlier version.
-
The app does not return results for federated share files.
-
The app only works with the default encryption module "Master Key".
