Liferay 7.0 - search for words with underscore
Expert Posts: 319 Join Date: 3/25/11 Recent Posts
Hi!


I'm using Liferay 7.0, and I need search to be able to find words with undescore ('_').
For example, seach for "development' should find documents/articles/etc. with 'liferay_development' title.

In 7.1 seach works in this way, but in 7.0 does not.

How can I achieve such functionality in 7.0 ?

¿Which search engine are you using in Liferay 7.0? ¿Elasticsearch 2.x, Elasticsearch 6.1 or Solr?

If you are using Elasticsearch 2.x perhaps you can try upgrading to Elasticsearch 6.1, as it is one of the changes included in Liferay 7.1, see:You have also to update your system to Liferay 7.0 GA7 or newer.

Thanks Jorge,

I was using default bult-in Elasticsearch, bundled with Liferay (ce-ga-4).
​​​​​​​Will try to upgrade to Elasticsearch 6.1.

Do NOT use embedded Elasticsearch in production. Embedded Elasticsearch is useful for development and demonstration purposes, but shouldn't be used in production environments.
For more information see: https://dev.liferay.com/discover/deployment/-/knowledge_base/7-1/configuring-elasticsearch-for-liferay-0#embedded-vs-remote-operation-mode

Jorge,



Thanks! We're already using a standalong Elasticsearch in production (and have lr 7.0 ga7). 

Is there a way for achieving this w/o updading Elasticsearch to 6.1?

Perhaps, it's possible to specify custom analyzer or tokenizer (to split word with '_' to individual search terms) ?

Vitaliy
