The Item Filters and
Content Filters that are available in the Model Manager search tools can be categorized based on the types of fields that they match on. These
field types affect, for example, how the field values specified in filters are interpreted when searching the database.
A filter on a text field matches search words in a text. Individual “words” in the text are obtained by splitting on spaces, punctuation markers, and other delimiter characters. Examples of text fields are the title and description of a model or file.
A filter on a keyword field matches a search word against a string value. Keyword fields are typically found for short, name-like, search data, such as the filename of a model or file.
A filter on a date field matches against a date and time value. You can specify the date and time format according to the localization rules for the language set in the COMSOL Desktop or according to the ISO-8601 standard format. An example of a date field is the last modified timestamp of a model or file.
Dates and times can either be matched exactly or as an interval. The intervals can be open on one or both sides. See also Range Matching. You can also specify intervals from a select set of
date shorthands. This includes, for example,
TODAY for the current day and
CURRENTWEEK for a date interval covering the current week. See
Table 3-6 for the complete list.
A filter on a numeric field matches on a real or complex scalar value. An example of a numeric field is the last computation time of a study, or a numerical setting or parameter value. The unit to use for dimensioned scalar values depends on the context.
A filter on a Boolean field matches on either
true or
false. An example is whether or not a 1D or 2D component is axisymmetric.
A filter on a selection field is a specialized filter that involves selecting values from a predetermined set. Examples include
Item Types and
Save Types of models or the user that last modified a model or file.
