Subject [jira] [Comment Edited] (FALCON-1095) Support free-text search for entities

--------------------------------------------------------------

Actually, matching with regular expression (including wild card matching) is the original
proposal. But Ajay pointed out that using regular expression symbols (e.g. *) 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 "*" 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.

> 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".
