Example:
Row 1: "machine learning" OR "artificial intelligence" OR "neural networks"
Row 2: "cyber crime" OR "computer crime" OR "cybercrime"
In ACM Digital Library, proximity searching allows you to return results with two or more terms with a specified number of words between them.
The example "machine learning"~10 will find results where "machine" and "learning" have up to 10 words between them.
By default, ACM Digital Library search is configured to use plurals and stemming (retrieving variations of a keyword that use the same root or stem). Wildcards should be used when you need to include variations that stemming might miss, such as irregular forms, different prefixes or suffixes, and alternative spellings. They also allow for enhanced customisation and precision, which is particularly useful when searching systematically.
Please note the following limitations:
By default, search is configured to use plurals and stemming (retrieving variations of a keyword that use the same root or stem). Therefore, phrase searching should be utilised wherever you require to interpret any single word or phrase literally.
Example:
"machine learning" returns results with the exact phrase (146,995 results)
machine learning returns results with machine OR learning (240,336 results)
The search operators AND and OR are used in searching to combine search terms together.
AND retrieves articles which contain all of your concepts. For example, if you are interested in the use of cognitive behaviour therapy for gambling disorders, you would search for cognitive behaviour therapy AND gambling.
OR retrieves records which contain any of your concepts. For example, you might search for cognitive behaviour therapy OR CBT to retrieve all articles on the topic.
