-When a search is performed, a search thread looks for matches in the RAM chunk and then on each disk chunk.
+When a search is performed, a search thread looks in each disk chunk (from oldest to newest) and lastly in the RAM chunk.
 The search becomes slower as the disk has more chunks, as a single search thread is used. 
 The effect increases with the number of disk chunks and it's more visible on slower storage.
 Multi-threaded searching over the disk chunks can be enabled by setting :ref:`dist_threads<dist_threads>` to a value greater than one.
-Depending on the value of dist_threads, a number of search threads will be launched in parallel and search over the disk chunks. 
-The search on the RAM chunk is not parallelized.
+When a search is invoked against a RT index, it pushes tasks to search over every disk chunk in the thread pool, all running in parallel.
+After all disk chunks searches finish, daemon continues the search process with the RAM chunk.
 
 Data in RAM chunk gets saved to disk on clean daemon shutdown, and then
 loaded back on startup. However, on daemon or server crash, updates from
