search builder

It's just that anything other than keyword search is a nightmare, because there's no kind of search builder.

Use the Advanced search Builder to search for terms in a specific search field.

Yahoo has introduced a similar product, called Search Builder, but Google says its service allows more customization.

Click Advanced to use the search builder, and then select Author from the All Fields menu.

To search for other fields in a citation, use the pull-down menus to select a field before entering a term in the search builder box.

The Advanced search builder Show index list provides an alphabetical display of all terms in each PubMed search field.

MeSH terms can be selected for searching in the MeSH database and from the advanced search builder index.

You may continue searching and including additional terms to the PubMed search builder using the "Add to search builder" and Boolean pull-down menu.

Microsoft's updated MSN Search tries to make searching easier by complementing Boolean terms like "and," "or" and "not" with slide controls (under "results ranking" in Search Builder) that can be adjusted to determine how broadly or narrowly to search.

To build a PubMed search from MeSH, run a search, select terms using the check boxes, and then click "Add to search builder" in the PubMed search builder portlet.
