 == Search for relevance
-Sometimes you might be unsure which documents best match your question. 
+Sometimes you might be unsure which documents best match your search.
 {es} assigns a relevancy, or score to each document, so you can
 can narrow your search to the documents with the most relevant results.
 The higher the score, the better it matches your query.
 
-For example, suppose you have the <<gs-get-data-into-kibana, sample flights data set>>, and you're a searching for
-a flight that arrived or departed from `Warsaw` or `Venice` when the weather was clear.
+This example shows how to use *Discover* to list
+your documents from most relevant to least relevant. This example uses
+the <<gs-get-data-into-kibana, sample flights data set>>, or you can use your own data.
 
-.  In *Discover*, open the index pattern dropdown, and select `kibana_sample_data_flight`.
-.  In the query bar, click  *KQL*, and switch to the <<lucene-query, Lucene query syntax>>.
-. Search for `Warsaw OR Venice OR Clear`.
-.  If you don't see any results, open the time filter and select a time range that contains data.
-.  From the list of *Available fields*, add `_score` to the document table.
-. In the document table, click the header for the `_score` column, and then sort the column by descending scores.
+.  In *Discover*, open the index pattern dropdown, and select that data you want to work with.
 +
-The results are currently sorted by first `Time`, and then by `_score`.
-. To sort only by `_score`, remove the `Time` field.
+For the sample flights data, set the index pattern to *kibana_sample_data_flights*.
+.  In the query bar, click  *KQL*, and then turn it off.
 +
-Your table now shows documents with the best matches, from most to least relevant.
+You're now using the <<lucene-query, Lucene query syntax>>.
+.  Run your search.  For the sample data, try:
++
+```ts
+Warsaw OR Venice OR Clear
+```
+. If you don't see any results, expand the <<set-time-filter,time range>>, for example to *Last 7 days*.
+. From the list of *Available fields*, add `_score` and any other fields you want to the document table.
+. To sort the `_score` column in descending order, hover over its header, and then click twice on
+the arrow icon
+image:images/double-arrow.png[Double arrow icon to indicate sorting] so it changes to
+image:images/downward-arrow.png[Downward pointing arrow to indicate descending sorting].
++
+At this point, you're doing a multi-column sort: first by `Time`, and then by `_score`.
+. To turn off sorting for the `Time` field, hover over its header, and then click the down arrow.
++
+Your table now sorts documents from most to least relevant.
