Question

Lets say I want to query for string “this is first title” and I want it to return almost similar strings like below.

this is first title
this is second title
this is third title

Is this possible with QueryOptions to query for “almost similar” string?

Answer 1

You can search for "this is" title (enclosing the “this is” in double quotes treats it as a phrase), which should work for your particular use case.
If you’re searching in a particular field, say ‘summary’, you can specify the field to narrow your search, e.g.: summary:"this is" summary:title

You can use the ‘~’ operator to rewrite queries to include plurals, which is one way of searching for similar text.
