3 months ago The definition of the LinkTypes can be found here - https://loinc.org/kb/enriched-linkages-between-loinc-terms-and-loinc-parts/ The search relationships are fragments and synonyms that can be used to help find terms. We use these relationships in Search LOINC to build out the index.

2 months ago Shahim and I met recently and looked into search a bit.
We looked into what properties search is used on. They are:
CHALLENGECOMPONENTMETHODSYSTEMSUPER SYSTEMSearch & grouping classes
It would be good to look at the LOINC parts that are used often in search. These are the biggest candidates for grouping.
We want to do an analysis; create a CSV of: loinc_part, property (optional), count
Overview
There are components, e.g. "Sodium Urate crystals", that can be broken down into multiple other, related components. However, relationships between these are not formalized in LOINC. The http://loinc.org/property/search property is used to denote the relationship of each of these sub-components, e.g. "Sodium", to the LOINC term Sodium Urate crystals [Energy Difference] in 24 hour Urine
101734-2. But, for example, there is no defined relationship between SodiumLP15099-2(LOINC:search) and Sodium urate crystalsLP18869-5(LOINC:analyte).We need to figure out how to define relationships between them.
Example case
Additional challenge
Some of these search components have relationships to each other that aren't as simple as "part of" (e.g. we could say that "Sodium" is part-of "Sodium Urate crystals". Take, for example, Sodium urate
LP35723-3and Urate crystalsLP32885-3, which seem related in that they have an intersecting qualifier UrateLP15935-7.
