General

Type your search terms in the four empty boxes, one or more per box. With the menus at the left of each box you can restrict to a specific field: author, title etc. The menus at the right determine what happens if the box contains more than one word:
all words: will return articles that contain all words, anywhere in the requested field any word: will return articles that contain at least one of the words in the requested field exact phrase: will return articles where the words appear as a continuous phrase in the requested field.

Wildcards and truncation

A question mark stands for any single character. An asterisk stands for any number of characters. These wildcards can be used at the end of a search term, and also at the beginning or in the middle of a word. The search may be slower in these cases.
Examples:
tumo* retrieves tumor, tumour, tumors, tumours, tumorigenisis, tumoricidal etc.
nf* retrieves NF-?B, NF?B, NF-kB, NFkappaB, NF1 etc.
j*son retrieves Johnson, Jonson, Janson, Jenson, Jackson, Johanson etc.
j?nson retrieves Jonson, Janson, Jenson etc., but not Johnson.

Authors

Use the format smith_cp. Author names are automatically expanded to include all combinations of initials, e.g. smith_c returns Smith C, Smith CA etc. You can turn this off by using quotes around the name, e.g. “smith_c” [au]

Article type

Use the Article types drop down to restrict the search to one article type published by this journal. false

Date

You can restrict to recent articles (published within a certain number of days), or you can restrict by year of publication.

Show results

You can use these options to order the results by relevance or date of publication and display more or fewer matches per page.

General

Queries can include the following Boolean operators:

AND, OR, NOT

A query that contains several different operators needs round brackets to remove ambiguities, e.g. osteoporosis and (alcohol or tobacco)

Append field names between square brackets to restrict a search to a particular field. Abbreviations can be found in the [List of field names]. Example: smith [au] and array [ti]

Use double quotes to identify phrases (e.g. "red blood cell").

The asterisk functions as a wildcard, replacing any number of characters (e.g. diabet* retrieves diabetes and diabetic). The question mark replaces one single character (e.g. j?nson retrieves Jonson, Jenson, Janson etc.)

Storing searches
The search history shows all the searches you have been running in the current session. It is emptied when you close your browser. To store a search for a longer period, click the 'store' button next to the query.

Combining searches
You can combine search numbers from the history with the operators AND, OR and NOT, e.g. #2 and #5 returns articles that are common to search #2 and search #5. You can also combine search numbers with new search terms e.g. #4 NOT jones [au] removes articles by Jones from the results of search #4. You can type combined searches in the advanced search form, or in the boolean search form (only the boolean search page has a list of field names).
