Search Options

You can specify three options to control the processing of your query:

The Match Option

The first option you can specify controls how the words you type are matched to the entries in the database. You have two choices: Example 1: You are interested in the health status of indigenous people. Searching for "indi" in the subject field with the default settings allows you to find entries on "Indians, North American", "Indians, South American", "indigenous population", and "indigenous health services".

The Format Option

The second option gives you a choice of format: Note that the address for correspondence was current at the time the entry was published, not necessarily at the time you are searching (see residential mobility, migration :-)

Example 1:You have just run a query using the short format and decide you would like to see the abstracts. Use the "Go back" feature of your browser (usually represented by a left arrow in the toolbar) to return to the query form, click on the radio button for "Long format", and press the "Search" button. The citations now appear in full glory.

The Max Hits Option

The third option controls the maximum number of citations that our engine will send you in each batch. The default is 25, but you can increase this number up to 100. Let's say you set it to n.

If your query returns more than n hits, we will show you only the n most recent citations, in reverse chronological order (as determined by their appearance in Population Index).

Immediately after the listing, you will see a button that allows you to get the "next n hits", continuing in reverse chronological order. Repeating this procedure allows you to retrieve all hits in batches of n.

Example 1: You run an author search on yourself and find 49 hits (well done!). The search engine will show only the most recent 25 ones. You go back to the form, type 50 in the Max Hits field, and press the Search button. The listing now includes all 49 entries, and you can print a nicely formatted version of your bibliography.

Example 2:A couple of students are not sure how to search for a particular subject. They set Max Hits to 10 to get a quick sense of the number and type of entries retrieved under various keywords. When they have focused on the target and have a search that will return 97 hits, they set Max Hits to 100, run the search, and save the output to disk for later examination.
