New tag for search apis as els, algolia, meilisearch, ..

As the options for open-source search-engine/search-api/site-search expands there is a need to define them with a tag.

For examples:

• Algolia
• ElasticSearch
• MeiliSearch
• RedisSearch

At the moment, the only relevant tag available is database which is not clear enough and also not true as most of these options are not ACID.

The most obvious tag would have been "searchengine" but SEO gave it another definition.

I would suggest one of the following to become an official tag:

• search
• search-engine
• search-api
• search-interface
