Field-Level Searches

If you know which field contains the information that you are searching for, field-level searches can help to reduce search time and also filter out extraneous results, and in less time than a free text search across all columns of the indexed data. For example, if you know that Opera is a value present in the user_agent field, you can run a field-level search for Opera values:

You can combine the field-level search criteria with AND, OR, and NOT syntax to create even more granular searches. For example, to search for the records that have a user_agent field that includes Opera and a cs_method field value HEAD:

The list reduces to about 18,000 hits. With a good use of field searches, you can reduce the results to create a faster and more granular result set for review.

The NOT syntax is a helpful way to filter out conditions. For example, to search for the records that have a user_agent field that includes Opera but do not have a cs_method field of HEAD:

user_agent:Opera AND NOT cs_method:HEAD
