+## Fulltext search
+
+Dendrite supports experimental fulltext indexing using [Bleve](https://github.com/blevesearch/bleve), it is configured in the `sync_api` section as follows. Depending on the language most likely to be used on the server, it might make sense to change the `language` used when indexing, to ensure the returned results match the expections. A full list of possible languages can be found [here](https://github.com/blevesearch/bleve/tree/master/analysis/lang).

+```yaml
+sync_api:
+  # ...
+  fulltext:
+    enabled: false
+    index_path: "./fulltextindex"
+    language: "en"
