There are several concepts related to search on the Cascade Server Knowledge Base. Below are links to our current search resources:

General Search Syntax Information
With the release of Cascade Server 5.7.3, users can now use wild cards and the following specific search characters to construct more powerful search queries:
+, -, !, (, ), {, }, [, ], ^, ", ~, *, ?, :, \
Technical
Detailed Search Syntax Information
These characters hold special meaning in search queries allowing logical combinations of search terms like (a OR b) AND c and search language features. In order to actually search for one of the special characters (e.g. they want to find "+" character), users will need to "escape" the special character by placing a \ in front of it. Therefore, the query to find the "+" character would need to look like this:
\+
or
*\+* (if we want to find + character that is not standing alone.)
If a user wants to find an asset with path "/path/to/asset", by typing just the end of the path "/to/asset", they will need to put a wildcard * before their query:
*/to/asset
If a user wants to find all assets in folder with path "/path/to", he will need to put a wildcard * after the query:
path/to/*
Paths in Cascade Server's search index are stored without the leading slash. Therefore, when looking for a specific asset with path "/path/to/asset" without wildcards a user should enter:
path/to/asset
instead of:
/path/to/asset
Search Syntax Examples
As was mentioned in the general search syntax information section above, it is now possible to look for assets that contain multiple terms at once. To do this, we use keyword AND. Therefore, in order to find a page that contains words "Mr" and "Smith" we use the following query:
Mr AND Smith
If you want to find all pages that contain either word "Mr" or "Mrs", we can use keyword OR:
Mr OR Mrs
If you want to find all pages that contain word "Smith" and either "Mr" or "Mrs", we should use parenthesis for that:
(Mr OR Mrs) AND Smith
Only keywords in the Cascade type-ahead search are case sensitive. If we want to find assets that contain the actual word "AND", we can simply use lowercase "and,"
and
which will not be taken as a keyword but will find all assets with occurences of "and", "And", "AND" etc.
The logical keywords AND and OR need text before them and after them. Query that ends with AND or OR will result with an error, like:
Something AND
will result with:
Could not parse the search query
in type ahead search. The full error message will appear when we submit the search (by hitting the "Enter" key). For example,
Search failed: Cannot parse 'Something AND': Encountered "" at line 1, column 13. Was expecting one of: ... "+" ... "-" ... "(" ... "*" ... ... ... ... ... "[" ... "{" ... ... ... "*" ...
It is also possible to find a specific phrase using the quotes. For example, we might want to find "Hello World!":
"Hello World!"
