Configure the Number Index Process

You can configure the IDOL Content component to index numeric and alphanumeric fields in several ways by using the configuration parameter IndexNumbers. Set IndexNumbers to one of the following values to specify how Content treats numbers:

0 Numbers are not indexed.
1 All numbers are indexed (irrespective of whether they appear on their own or as part of a word).
2 Numbers are indexed only if they are part of a word (for example DRE4, Y2K and so on).

To restrict this to a narrower set of data, use the field processing property IndexNumbersType. Create an IndexNumbersFields section and specify which fields qualify. You can limit only terms that are indexed within the field property.

For example:




This means that Content indexes the numeric terms in */MYFIELD that satisfy IndexNumbers=2 (non-numeric and mixed-alphanumeric), whereas all other fields index with IndexNumbers=1 (all numeric terms).


If the IndexNumbers configuration parameter is not specified in a property section, its default is 0.

You can also limit the indexing of numeric or mixed-alphanumeric terms by the length of the term.

For example:


This means that fields with this property have all numbers indexed, assuming the language has IndexNumbers=1 configured, except for pure numeric terms longer than five characters, which are not indexed. Alphanumeric terms longer than six characters are also not indexed.


You cannot set the length to more than 255.
