The Full-Text Search feature provided by the Control Panel allows you to search for the necessary string not only among the names of documents, emails etc. but also within their content.
ONLYOFFICE uses Elasticsearch, an open-source, broadly-distributable and readily-scalable search engine. Elsaticsearch is built on top of Lucene, a free and open-source search engine software library, and, therefore, it is excellent for fast full-text search.
The documents stored in Elasticsearch are distributed across different containers known as shards, which are duplicated to provide redundant copies of the data in case of hardware failure.
Using Elasticsearch not only significantly reduces the time spent searching for a particular file or a text line but also enhances the search precision.
