Which search string matches only events with the status_code of 4:4?

The search string statuscode>403 statuscode 403 AND statuscode < 405. When evaluating numeric fields, the only integer value that satisfies both conditions (being greater than 403 and less than 405) is 404. This method effectively and exclusively filters for the desired events.

A. statuscode !=404 is incorrect because the != operator excludes all events with a statuscode of 404, which is the opposite of the requirement.
B. statuscode>=400 is incorrect because it matches a broad range of values, including 400, 401, 500, etc., not only 404.
C. statuscode<=404 is incorrect because it matches a broad range of values, including 403, 200, 301, etc., not only 404.

"Boolean expressions": This document confirms the implicit AND logic. It states

"The AND operator is implied between terms. For example

searching for weblogic system is the same as searching for weblogic AND system." This principle applies to the two expressions in the correct answer.

"search command": This reference details the syntax for the search command

including the use of comparison operators. Under the "Syntax" section

it lists the valid comparison operators as =

!=

<

>

<=

>=. The answer uses > and < to create a specific numeric range.

"Module 5 - Using Fields": This official course material explains how to use fields in searches

including filtering with numeric comparison operators to narrow down search results. It provides examples of using >

<

and = to find events based on specific numeric field values

which is the core concept tested in this question.
