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 and Advanced searches. 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).
