--------------------------------------------------------------
Actually, matching with regular expression (including wild card matching) is
the original proposal. But Ajay pointed out that using regular expression
symbols (e.g. wild card) doesn't make API user-friendly (see comments above). I
also think that using subsequence is better since it saves users' time by not
typing extra wild card characters in the query and thus makes search simpler.
That's how we keep subsequence matching. I'll include detailed explanation in
our API documentation. Thanks for pointing it out.

> Support free-text search for entities
> -------------------------------------
>
> Key: FALCON-1095
> URL: https://issues.apache.org/jira/browse/FALCON-1095
> Project: Falcon
> Issue Type: New Feature
> Affects Versions: 0.6
> Reporter: Ying Zheng
> Assignee: Ying Zheng
> Fix For: 0.7
>
>
> When users have hundreds or thousands of entities to manage, they may not
> remember the exact name/tag of the entity. We would like to provide a more
> convenient way for the user to search an entity by providing keywords in name
> and tags. We also plan to provide a search UI, similar to Visual Search, to
> allow the user to enter keywords in a search box and display the filtered
> results. The user can click on the entity to view details and search its
> instances as well.
> To support free-text search, we plan to extend the LIST API:
> GET api/entities/list/:entity-type
> Parameters changed/added:
> 1) :entity-type Valid options are cluster, feed, process and all. Here
> "all" represents feeds and processes.
> 2) nameseq Subsequence of entity name. Not case sensitive. Example:
> "Sample1" is a subsequence of entity name "SampleFeed1". Note that we rename
> "pattern" parameter to "nameseq" to make it more intuitive to the user, but
> the functionality is already there in Falcon-914 .
> 3) tagkey Tag keywords, separated by comma. Not case sensitive.
> Results
> Return the total number of entity results and a list of entities.
> e.g. falcon entity -list -nameseq housetexas -tagkey estate
> This should return the entity with name "houseSellTexas" and tags
> "category=realestate".
