EMERSE utilizes the blazingly fast, open-source Solr search engine
. This allows for iterative search refinements in real-time.
In 2019 a test was conducted to compare the response time of EMERSE in identifying a cohort of patients (unique patient count) compared to
the response time of querying the Epic Clarity database running on Oracle. Results are below.
||Epic Clarity time
||EMERSE Solr time
|gray platelet syndrome
|inferior lingular segment of the left upper lobe
* This was a wildcard search (the * represents a wildcard).
Note: A "proper" Clarity search has to concatenate rows for words/phrases split between database rows and would likely take longer than the estimates shown above.
