You can set constraints for the spelling dictionaries in Developer Studio.
By default, Dgidx examines dimensions and properties enabled for search and adds words that are larger than 3 characters and smaller than 16 characters to the dictionary. However, because performance of spelling correction in the MDEX Engine depends heavily on the size of the dictionary, you can set constraints on the contents of the dictionary. For example, you might choose to either increase the default from a minimum of 3 characters or reduce the default from a maximum of 16 characters. These configuration settings are useful for improving the performance of spell-corrected search operations at runtime.
These configuration options can be used to tune and improve the types of spelling corrections produced by the MDEX Engine. For example, setting the minimum number of word occurrences can direct the attention of the spelling correction algorithm away from infrequent terms and towards more popular (frequently occurring) terms, which might be deemed more likely to correspond to intended user search terms.
To configure spelling dictionary entries:
You can separately configure entries in the dictionary based for dimension search and record search. Therefore, select either the Dimension Search tab or the Record Search tab.
In this example, the Dimension Search tab is selected.
Set the constraints for adding words to the spelling dictionary:
Field Description it occurs at least n times Sets the minimum number of times the word must appear in your source data before the word should be included in the spelling dictionary. and is between n1 and n2 characters long Sets the minimum (n1) and maximum (n2) lengths of a word for inclusion in the dictionary. If desired, select the other tab and set the constraints for that type of search.
