On this page, you will find information on search strategies and other tips that can help you to retrieve better search results from databases and other search tools.
Here you find examples of some search strategies to use when you are searching for information. It is often a good method to begin the search process with basic test searches before moving on to more structured search strategies. You will find more about the information searching process at the page Search tips in this guide.
This is an example of a building blocks search in the database ABI/INFORM Collection where Boolean operators, truncation, and phrase search has been used. Each row (block) contains terms that are related to each other: terms that have to do with product quality and terms that have to do with consumer perspective - with the search operator OR between each term. The blocks are combined with the search operator AND between the rows.
It is important that each block is put into separate rows in the search form. It is dificult to use several search operators in one and the same row (like in this example, AND and OR). If you still want to do this, you have to separate the blocks with parentheses:
("product quality" OR "quality of products") AND ("consumer* perspective" OR "consumer* perception" )
This search will give the same search results as the one in the search form above.
This method of presenting search strings by using parentheses is suitable to use if you have to present your searches, for example when you are writing a literature review.
This is an example where the search history has been used as a search strategy in the database Business Source Premier. It shows searches on single terms and how the functionalities in the database have been used to combine the searches with OR and with AND into more complex search strings. This search strategy lets you perform highly structured searches. You can view the results from every search and evaluate the relevance of each search term.
Start with highly relevant documents, the "pearls" that you already have found. Perform further searches from information available in these documents and in their database records. Use information like keywords, subject headings, author names, references, citations and related documents.
Use the bibliography ("View references") to chain information backwards - use the citations ("View citing documents") to chain information forewards.
Several databases allow you to use proximity operators to search for terms close to each other in titles, abstracts, and full texts.
Use proximity operators when a search with AND textiles AND substrates is too broad while a phrase search ”textile substrates” is too narrow.
The proximity search (example - Scopus) textile W/5 substrates give results with both the words in any order, with up to 5 words between them. Such a search will cover formulations like:
textile substrates
textiles and other substrates
substrates such as textiles
Often, there are also proximity operators for searching terms close to each other in a specified order, with up to a specified number of words between them. Example breast PRE/1 pocket covers both breast pocket och breast welt pocket.
Example - Scopus:
Each database uses different proximity operators:
