- Note: _ is used here to separate two symbols which are not separated in the real query.
q=(index_operator_"searchvalue" logic not index_operator_"searchvalue") logic not (index_operator_"searchvalue" logi index_operator_"searchvalue")
q=searchvalue
Examples
Operators
- Operators are represented in the query template by symbol: operator
- The supported operators are:
- = : this is the basic equal. Means that a regular expression search will be performed
- == : This is the exact search. Only exact matching result will be find. Useful when searching for an uri (to find a specific resource)
- =< : lesser than. Works only if the search object type is compatible with search a search (number, date)
- => : greater than. Works only if the search object type is compatible with search a search (number, date)

Search value
- Search values are represented in the the query template by: searchvalue
