 The NRC-Adams Licensing Support Network Library, How-To video series, Advanced Search using search terms, dates, and record properties. The Advanced Search tab can help you narrow results by combining search terms, dates, and record properties. Click on the Show Advanced tab to pull down the Advanced Search window. The top four boxes allow you to search with terms in different ways. If you enter desert tortoise into all of these words field and activate the search by clicking on the magnifying glass, the LSN library finds records with both desert and tortoise in them, over 11,000 records. Putting desert tortoise into any of these words field will locate records that contain either desert or tortoise in them, a much larger group of documents. Putting desert tortoise into the exact phrase field narrows the results to those where desert tortoise appear right next to each other. The last of the top four boxes labeled none of these words excludes words from the search. For example, you could exclude from the desert tortoise search records that mention the Nuclear Regulatory Commission by adding NRC. You can limit results by adding a date range in the start date and end date fields. For example, adding a start date of January 1, 1997 and an end date of June 30, 1997 reduces your results a lot. Dates can also be entered by using the pull down calendars. The field query narrows a search by taking advantage of what are called a records properties. When each record was added to the LSN library, properties such as the author affiliation, author name, document type, information source and title were added into separate fields. So you can limit a search for desert tortoise records to those produced by just one author. Select author name under the field query window and type in a name. This reduces the original results to just those written by this expert, Danny Raikstra. Similarly, a title search will limit your results to just those where search words appear in the records title. Under the field query pull down menu, select title and type in desert tortoise. This search reduced your original 11,000 results substantially.
