The modified broad matching could be enabled simply by adding a plus sign (+) in front of one or more words of a broad matching keyword phrase;
Each word preceded by a + has to appear in your potential customer's search exactly or as a close variant. Close variants include misspellings, singular/plural forms, abbreviations and acronyms, and stemming (like “floor” and “flooring”). Synonyms (like “quick” and “fast”) and related searches (like “flowers” and “tulips”) aren't considered close variants.
In the illustration above, in each ring the keyword shown also matches the searches inside the smaller rings, and that is how exactly the system works.
If you're in Canada or the UK, you can log into your AdWords account to start adding modified broad match keywords today. You can also use the AdWords Editor or the AdWords API. For more details, examples, suggestions on usage, and answers to many common questions, visit the AdWords Help Center.
