+## Queries on analyzed text
+
+When running queries, understanding whether your fields are analyzed ([`text`]({{site.url}}{{site.baseurl}}/field-types/supported-field-types/text/) type) or non-analyzed ([`keyword`]({{site.url}}{{site.baseurl}}/field-types/supported-field-types/keyword/) type) is crucial because it significantly impacts search behavior. In analyzed fields, text undergoes tokenization and filtering, while non-analyzed fields store exact values. For simple field queries like `wind`, searches against analyzed fields match documents containing `wind` regardless of case, while the same query on keyword fields requires exact matching of the full string. For more information about analyzed fields, see [Text analysis]({{site.url}}{{site.baseurl}}/analyzers/).
