Phrase Searching Phrase searching using quotation marks is recognized. Ranking Results are ranked, and appear in order according to the number of highly rated pages which have linked to the page in question, and which best match the terms searched. Depending upon which search engines are contacted, symbols, parentheses, quotation marks and other limiting symbols may be used. The symbols are automatically removed when the individual search engine does not permit them or recognize their use, and the results from these search engines may be skewed accordingly. Most metasearch engines have both time constraints and restrictions on the number of results returned by each individual engine.
Individual engines allow more precise manipulation of the data entered.
