Compatibility Considerations

New features and changes introduced in Version 7.3 (R2006b) are described here.
Exact Phrase and Wildcard Searching Added; Change to Search Database
These improvements were made to the Help browser search feature. Note that they are
not supported on Japanese systems.
• Search Field Always Shown — The Search for field is now always in view when the
Help browser is open. The list of pages found appears in the Search Results tab.
• Exact Phrase Searches for More Relevant Results — Find an exact phrase by typing
quotation marks around the search term. For example, "plot tools" finds only
pages that include plot tools together, but does not find pages that include plot in
one part of the page and tools in another part of the page. You can specify more than
one exact phrase in a search term, such as "plot tools" "figure pallette".
• Wildcards (*) in Search Terms for Variations of a Word (Partial Word Search) —
Use the wildcard character (*) in place of letters or digits in your search terms. For
example, plot* finds various forms of the word plot, such as plot, plots, and
plotting, while p*t find those variations as well as variations of print and part,
among others. You can use multiple wildcards in a word or search term.
• Boolean Operator Evaluation Order Changed — Boolean NOT operators in search
terms are now evaluated first, followed by ORs, and then ANDs. In prior versions,
Boolean operators were evaluated in left to right order.
Compatibility Considerations
The search enhancements were facilitated by changing to a new type of database. As a
result, any existing Help search databases for non-Mathworks products will not work in
R2006b and beyond. The documentation still displays in the Help browser, but it is not
included in searches.
If you use Help browser documentation for non-MathWorks products with a pre-R2006b
search database, a message will display in the Help browser to notify you that the
