Summary: Search using entity and trait attributes - Issue with
Boolean attributes of tag and case insensitive search
Key: ATLAS-2036
URL: https://issues.apache.org/jira/browse/ATLAS-2036
Project: Atlas
Issue Type: Bug
Components: atlas-core
Affects Versions: 0.9-incubating
Reporter: Sharmadha Sainath
1. Created a tag tag1 with attributes
1. strAttr of type string ,
2. boolAttr of type boolean ,
3. intAttr of type integer
2. Associated an entity to the tag with values =
strAttr : value
boolAttr : false
intAttr : 5
3. In Basic search :
a) tag = tag1 ,
tagfilters :
strAttr = value fetched the entity
b) tag = tag1 ,
tagfilters :
strAttr= VALUE fetched the entity
c) tag = tag1 ,
tagfilters :
strAttr = value ,
boolAttr = false ,
intAttr = 5 fetched the entity
d) tag = tag1 ,
tagfilters :
strAttr = VALUE ,
intAttr = 5 fetched any entity
e) tag = tag1 ,
tagfilters :
boolAttr = false fetched any entity
e) But tag = tag1 ,
tagfilters:
strAttr = VALUE ,
boolAttr = false didn't fetch any entity . (to be noted : strAttr's
value is in CAPS)
Logs when searching for tag filters : strAttr : VALUE , intAttr:5

WARN - [pool-2-thread-9 - 4c272ca0-4853-4d24-b2d0-f10934516889:] ~ search
includes non-indexed attribute 'tag1.boolAttr'; might cause poor performance
(SearchProcessor:120)
{code}
Thus , any case insensitive string search with boolean attribute in tag search
fails to fetch the entity. Other datatypes (including enum) when combined with
case insensitive search fetches the expected entity.
Also , this behavior is not observed on entity filters.
For example , an hdfs_path entity with description - hdfs_path , isSymLink =
false ,
both the following search fetch the entity :
1. description = hdfs_path , isSymLink = false
2. description = Hdfs_path , isSymLink = false
