Add Filter semantic Tag

[GokulRamasamy]

How to search term based on semantic tag.
eg: I want to search 'heart attack' term from disorder semantic tag.

Hi there. There are two ways to achieve searching within a specific area of the hierarchy; using ECL or using a semantic tag filter.

ECL Method
Combine an ECL structural search with a term search using the concepts endpoint:

GET /{branch}/concepts?ecl={ecl}&term={term}

For example:

GET /MAIN/concepts?ecl=<64572001&term=heart%20attack

This will return concepts which are descendants of 64572001 |Disease (disorder)| and also have a description matching the term query. Prefixes of words can be used in the term param for example myo infar can be used to match Myocardial infarction

Semantic Tag Filter
The semantic tag filter is only currently available on the develop branch of this project. It is scheduled to be released in Snowstorm version 3.x
If you wanted to use the develop branch you can test it now using the following endpoint:

GET /browser/{branch}/descriptions?semanticTag={semanticTag}&term={term}

For example:

GET /browser/MAIN/2019-01-31/descriptions?semanticTag=disorder&term=heart%20attack

When reading the response scroll down through the aggregations to the items section to see the results.

Hi,
Thanks for your support.
Exactly I expected semantic tag filter in descriptions. (GET /browser/{branch}/descriptions?semanticTag={semanticTag}&term={term})
ECl query also working fine.
When will we expect snowstorm version 3.x?

The first 3.x release is currently planned for the beginning of May.
