|---|---|
| Find results with all the words | Words entered into this field must be present in a document for that document to be returned. Words should be entered with spaces between them. example: living environment |
| with the exact phrase | Enter an entire phrase into this field. The entire phrase must be present in a document for that document to be returned. If only a single word is entered in this field it will be treated as if it were entered in the "Find results with all the words" field. example: every cell is covered by a membrane |

If only a single word is entered in this field it will be treated as if it were entered in the "Find results with all the words" field. example: atlas benchmarks |
| without the words | Words entered in this field must not be present in a document for that document to be returned. At least one of the above fields must be used in conjunction with this field. example: textbook |
| Language | This function is not implemented. If an option other than "any language" is selected no results will be returned. |
| Domains | This field allows you to limit the location from which documents will be retrieved. Enter the domain or URL stem you would like to use. You can choose to search only within the location specified (choose "Only" from the drop-down) or to search every other location (choose "Don't" from the drop-down). The domains are limited to those indexed by the AAAS search engine (such as aaas.org and project2061.org). example: project2061.org |
| Sort | You can choose to sort the results by relevance or by date. Sorting by relevance will show documents with the highest probability of meeting your criteria first. Sorting by date will show the most recently updated documents first. |
| Sources | This lists the available document indexes. At least one source must be selected. At present only one source is available. |
| Return | This drop-down list allows you to choose the number of results to return. |
| Timeout | This drop-down list allows you to specify the maximum amount of time the search engine will use when performing your search. The search engine will only take as much time as needed up until this limit. If a search requires more time than is specified here the search engine will halt processing of the request and return the results it has available. Most searches can be done within the default timeout period. |
| Filter | This function is not implemented. If an option other than "no filtering" is selected no results will be returned. |
