== Search for relevance
|
|
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.
|
|
|
|
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 that data you want to work with.
|
|
+
|
|
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.
|
|
+
|
|
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/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.
