Subject [jira] [Commented] (FALCON-1095) Support free-text search for entities
Date Sun, 10 May 2015 01:45:00 GMT

    [ https://issues.apache.org/jira/browse/FALCON-1095?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14536986#comment-14536986
] 

Srikanth Sundarrajan commented on FALCON-1095:
----------------------------------------------

My 2 cents. The current proposal is to support the following as per FALCON-1121

{noformat}
Optional Args : -fields <<field1,field2>> 
-nameseq <<namesubsequence>> -tagkey <<tagkeyword1,tagkeyword2>>
-filterBy <<field1:value1,field2:value2>> -tags <<tagkey=tagvalue,tagkey=tagvalue>>
-orderBy <<field>> -sortOrder <<sortOrder>> -offset 0 -numResults
10
{noformat}

It seems to be getting very verbose and avoidable complex and may make it hard for users to
use this. I suggest we try and do something simpler and more intuitive.

{noformat}
-filter "field:value,field2:value2..." - search "free-text-to-search-anywhere-in-the-entity"

-orderBy <<field>> -sortOrder <<sortOrder>> -offset 0 -numResults
10
{noformat}

> 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 schedulable. Here "schedulable"
includes 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) tagkeys        Tag keywords, separated by comma. Not case sensitive. The returning
entities must have tags that match all the tag keywords.
> Results
>     Return the total number of entity results and a list of entities.
> e.g. falcon entity -list -nameseq housetexas -tagkeys estate
> This should return the entity with name "houseSellTexas" and tags "category=realestate".
