Meta-search forms are like personal shoppers. But on the Web, they work for free, offering the maximum level of convenience. They spend a lot of time thinking about shopping. EZ-Find at the River is one such service. They are labor-saving devices.
Searchers type their queries once, they push a single button once the text is entered.
Sites like EZ-Find may offer a thin layer of syntax conversion, that is, the service tweaks your text a bit, formatting your query into one suitable for the different search engines. These sites sometimes offer a compilation of results. Some such sites offer a separate form for each available search engine, allowing users to develop individual strategies for the search engines with which they are familiar. The problem with using these convenient devices is that your search is treated differently by each of the search sites. Each search engine has its own syntax, or search language.
