Keyword Occurrence Search
You can restrict the documents matching a query term to documents in which the number of occurrences of the term or phrase is within a specified range. Specify the range with a colon-separated pair of numbers. The maximum value that you can specify in the range is 32000.
For example:
http://localhost:5552/action=Query&Text=Gene[3:7]
This query returns only documents in which Gene appears between three and seven times (inclusively).
http://localhost:5552/action=Query&Text=”Gene Therapy”[5:8]
This query returns only documents in which the phrase Gene therapy appears between five and eight times (inclusively).
http://localhost:5552/action=Query&Text=Gen*[2:4]
This query returns only documents in which a term that starts with Gen (such as Gene or Generation) appears between two and four times, inclusively.
http://localhost:5552/action=Query&Text=(Gene OR DNA)[4:8] AND Therapy
This query returns only documents in which the term Gene or the term DNA appear between 4 and 8 times (inclusively), and the term Therapy occurs.
You can specify open-ended ranges. For example:
http://localhost:5552/action=Query&Text=Gene[10:]
This query returns only documents in which Gene appears 10 or more times.
You can also specify term weights and field restrictions. For example:
http://localhost:5552/action=Query&Text=cat[2:4]:DRETITLE + AND + cat[100][2:4]
