---------------------------------------
Summary: Update handling of special characters in query-value for
index-search
Key: ATLAS-3983
URL: https://issues.apache.org/jira/browse/ATLAS-3983
Project: Atlas
Issue Type: Improvement
Components: atlas-core
Reporter: Madhan Neethiraj
Assignee: Madhan Neethiraj
When query-value contains special characters, {{+-&|!(){}[]^"~*?:\/}}, Atlas
skips index-search and switches to graph-query, which could be expensive.
Index-search can still be used by escaping the special characters with a
backslash, per following Lucene documentation
[here|https://lucene.apache.org/core/6_5_1/queryparser/org/apache/lucene/queryparser/classic/package-summary.html#Escaping_Special_Characters]:

Escaping Special Characters
Lucene supports escaping special characters that are part of the query syntax.
The current list special characters are
+ - && || ! ( ) { } [ ] ^ " ~ * ? : \ /
To escape these character use the \ before the character. For example to search
for (1+1):2 use the query:
\(1\+1\)\:2
