> 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]:
> {noformat}
> 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
> {noformat}
