Does Elastic Search find synonyms and paraphrasing like Google?

[Alpha1]

If synonyms or paraphrasing is used then it is extremely hard to find something with a normal search engine. Google has resolved this by taking such into account. If you search for "bulletin board software compatible with newest PHP version" you will also get results about "message board software compatible with latest webserver software". A normal forum search engine will not find such synonyms or paraphrasing. For a community this is a major issue because a mass of members will use a lot of synonyms and paraphrasing and often content therefore will not be in search results.


Does Enhanced Search offer any solution to this problem?
If so do we need any special edition or settings?

ES can support synonyms, however these have to be defined by the webmaster. http://www.elasticsearch.org/guide/reference/index-modules/analysis/synonym-tokenfilter/

I see. There is no way that a webmaster can create a full list of all possible synonyms that millions of users may use or search for. Is there a premade list somewhere?

 

[Slavik]

No idea.

OK. I will file a suggestion for this as synonym support would greatly increase XenForo search engine effectiveness.

Does Xenforo record search terms ? (ie. record what is actually being searched for ?)(ie. in a table somewhere)

When adding synonyms you definitely want to start with the most commonly searched terms.

Where in ES can I add synonyms? The link above no longer works.

I see now that I need to add a configuration file somewhere in which I should define the location of a file with synonyms. I am not sure where. Does anyone know?
The file with synonyms should have the following SOLR syntax: https://www.elastic.co/guide/en/elasticsearch/reference/5.4/analysis-synonym-tokenfilter.html

And last but not least: does this work with XenForo Enhanced Search or is this not supported?

The file should be located relative to the config file. Normally that would be /etc/elasticsearch/elasticsearch.yml, eg /etc/elasticsearch/analysis/synonym.txt

I dont see why it wouldn't work with Enhanced Search as the change is all on the elasticsearch side
