You can increase the relevance of the results by using the NEAR proximity operator to capture articles that mention specific topics within a specified distance, where distance is the number of intermediate words or characters.
For example, a search could be used to find "red brick house", and match phrases such as "red house of brick" or "house made of red brick".
By limiting the proximity, these phrases can be matched while avoiding documents where the words are scattered or spread across a page or in unrelated articles in an anthology.
