Quick Tips

Each month we will be providing you with a new quick tip on the use of our products or how to navigate our website, as well as documents with links to further information (where applicable). If you have a suggestion for a tip, please let us know using the feedback details below.

Term filters with ECL

The NCTS supports filtering of ECL expressions with text strings. This is an experimental feature specific to Ontoserver, but useful for fine-tuning queries. The filter is invoked using double braces, as illustrated below.

<44027008|Seafood| {{term = "prawn"}}

For more complex expressions, parentheses are required around the ECL to be filtered:

(<28647000|Meat| MINUS <<226982009|Offal|) {{ term = "roast" }}

And multiple expressions can be combined with their own filters to produce progressively complex queries:

(<44027008|Seafood| {{term = "prawn"}})
OR ((<28647000|Meat| MINUS <<226982009|Offal|) {{ term = "roast" }})
OR (<227682004|Dessert|{{term="Christmas"}})
OR (<<35359004|Family| OR 113163005|Friend|)

These filters will match any term associated with a concept, and are case insensitive. You can experiment more with the Shrimp Browser.
