-------------------------------------------------------------
Thanks for asking about this, Scott.
This "subsequence" model is not new for falcon. It was already done by
[~ajayyadava] in Falcon-914 as "pattern" parameter. We just rename it to
"nameseq", but the functionality is already in Apache falcon code base. When I
talked with Ajay, he also likes this new naming, as it distinguishes name
filters from tags. I updated this in the description as well.
Regarding your question on the use of "subsequence" search model, one example
is IntelliJ. They provide subsequence search for classes, which makes it a lot
easier to search for the exact class name in a big collaborative project. We
expect the user to type useful hints or complete words in the name to take the
full advantage of this search functionality. We also think it is a reasonable
assumption that the user know certain order of keywords in the name. Any good
suggestions from you would be appreciated.

> 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".
