Although the code is searchable by key word or phrase, the search function can only find what you put in.
Suppose you are looking for information on trash collection. Technical terms change through the years, and instead of trash, there could also be code references under rubbish, garbage, refuse, and solid waste. Similarly, all references to a single subject may not be collected in one location and citations can appear in different sections because of the relationship of those sections to other city ordinances.
For the best results, pick up search terms from the descriptive language in the section you are reading to find other sections that relate to the same topic.
