Basic Search Syntax
Last Updated: 2020-06-12 (10 months ago)
The search syntax is similar to that of Google. Basic searches will follow the rules outlined below.
- Searches are case-insensitive so an upper case search term will return the same results as a lower case search term.
- Search terms will be separated by the AND operator when no operator is specified.
The following special characters can also be used in a basic search.
||The phrase in quotations is considered as a single search term rather than two independent terms.|
||Both terms must exist somewhere in each search result. As stated above, AND is implied when no operator is specified between search terms. In addition, the "+" operator has the same function as AND (see the Advanced Search Syntax section). So searching for morphine AND cutoff will produce the same search result as morphine cutoff or morphine +cutoff.|
||Either of the terms exist somewhere in each search result.|
||Excludes records that contain the term after NOT. The NOT operator cannot be used with only a single search term. In addition, the - operator has the same function as NOT (see the Advanced Search Syntax section). So searching for influenza NOT equine will produce the same search result as influenza -equine.|
||Single character wildcard search. Cannot be used in phrases. The ? operator is particularly useful when searching for a LOINC code when you do not remember the check digit. For example, 80619-? is a valid search that will return the row for LOINC 80619-0.|
||Multiple character wildcard search. Cannot be used in phrases.|
||When performing a search you can either search across all indexed fields, which is the default, or you can search for a value in a specific field using the syntax "FieldName:".|
See the Basic LOINC Field Names section and the Basic Part Field Names section for a list of the basic field names for LOINC term and part searches, respectively. See the Advanced LOINC Field Names section and the Advanced Part Field Names section for a list of the advanced field names for each type of search.
Component:opiates confirmwill look for opiates in the Component field and confirm in all of the indexed fields.
