== Search for relevance
|
|
Sometimes you might be unsure which documents best match your question.
|
|
{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.
|
|
|
|
. 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.
|
|
+
|
|
The results are currently sorted by first `Time`, and then by `_score`.
|
|
. To sort only by `_score`, remove the `Time` field.
|
|
+
|
|
Your table now shows documents with the best matches, from most to least relevant.
