A text search allows for searching of many of the database text fields, DICOM image tag data, and annotation files that are not available in the Simple search. Refer to the DICOM Data Dictionary for tags or field names you can use in a text search. A simple example of a text search is to find all subjects associated with the value pancreas by typing pancreas in the Text Search box. You can also use the field:searchTerm technique; for example, Body Part Examined:pancreas. In this example, the colon interprets the DICOM field from the value. Since text search also recognizes DICOM codes, you can also search on 0018,0015:pancreas, which is the DICOM code for Body Part Examined. Additionally, you can use a wildcard search such as Body Part Examined:panc* to find all subjects associated with values beginning with panc, including pancreas, pancreatic duct, and pancreatic duct and bile duct systems.
Text search does have some restrictions. These are:
- The text string you use must have more than one character. The search won't return any values if the text string has only one character.
- Do not use a forward slash (/) in your text string.
- Do not use complex searches with AND or OR statements (text search supports Lucene syntax but only a single field can be searched at a time).
