Bottom line: Write the intended result population before combining search conditions. Use explicit grouping for an exception instead of assuming how an ungrouped expression will be interpreted.

\n

Source fact: documented behavior

\n

The Filtering data using Wazuh Query Language (WQL) guide describes case-sensitive filtering and permits only lowercase and and or separators.

\n

Parentheses give the enclosed expressions priority, treating them as a unit inside the wider query.

\n

The guide requires double quotes around values containing spaces or quotation marks and says the * wildcard is unsupported.

\n

What the source does not establish

\n

This article concerns dashboard query construction. It does not establish an undocumented precedence rule for unparenthesized expressions, translate every dashboard operator into server API syntax or prove that the collected data is complete.

\n

Applicability questions

\n\n

DSE recommendation: controlled next steps

\n

The following steps are DSE recommendations based on the cited source.

\n

DSE recommends an explicit membership test for each grouped dashboard query before it is reused in an investigation.

\n
    \n
  1. Describe a proposed search in ordinary language first. For example, require two properties together while permitting one separately identified exception. Assign a harmless known record to each intended branch. Write down the excluded combination too, so a broad result list cannot be mistaken for a correct result merely because it contains a familiar record.
    2. \n
  2. Build the grouped expression through fields supported by the actual dashboard tab. Keep the intended pair inside parentheses and review the exception outside it. Check separator case and quotation of multiword values. Avoid introducing a wildcard to compensate for a misspelled value or copying the punctuation of a server API example into a dashboard search without its own documented translation.
    3. \n
  3. Ask another investigator to predict membership from the written requirement before seeing the returned results. Compare that prediction with the grouped expression, then with the actual search. Resolve disagreements by checking the field and record evidence. Preserve the accepted query with its interface context rather than saving an unexplained string that another analyst must reverse engineer.
    4. \n
\n

Verification and evidence

\n

Proposed verification: prepare a small approved record set with a match for both required properties, a match for only one, the named exception and an unrelated control. Record the intended membership before querying. Run the explicitly grouped expression and reconcile every returned or absent control against that plan. Do not assert that these fixtures have been loaded or queried.

\n

Then examine a permitted multiword value and a deliberate field-name or case error separately. Retain the displayed validation or search observation, redacted query and known-record references. A correct grouping test supports that query and population; it does not certify all Wazuh data, every dashboard tab or any untested API representation.
