Expression quotas is the term used for quotas based on numeric or text responses. (You can also use them for quotas based on specific combinations of characteristics, such as teenagers who have a weekend job and who visit the cinema at least twice a month.) You can define any number of expression quotas which may or may not be related to one another. For example, if you want to define quotas for a numeric question, you would define a set of expressions that group the possible responses into ranges so that you can set targets for each range. If you want to define quotas for a text question, you might define expressions that specify a word or words that must appear in the response text.

When UNICOM Intelligence Interviewer - Server checks an expression quota, it increments the counters for each expression that matches the respondent's answer. With numeric response ranges, the ranges are usually the equivalent of single categorical responses, so only the counters for one range will be affected. With quotas based on text responses (or combinations of responses) it is possible that more than one set of counters may be incremented if the respondent satisfies more than one expression.
