Ei Compendex is the electronic equivalent to printed Engineering Index, containing references and abstracts to over 5000 engineering journals and conferences. About half the citations (from 2600 journals and conferences) include abstracts and indexing in the records. The highest percentages of journal literature are in the fields of chemical and process engineering (15%), computers and data processing (12%), applied physics (11%), and electronics and communications (12%) In addition Compendex includes civil engineering (6%) and mechanical engineering (6%). Online coverage is from 1970 to the present, and files are updated weekly.

- If you don't specify a field to search, your query will be searched across the entire record. This contrasts with a Keyword search, which searches the title, abstract, and controlled vocabulary fields (including free language terms, also known as identifiers).

- Truncation is a method of finding multiple endings or forms of a word. The truncation character is *.
Boolean & Proximity Operators Operator Example Explanation AND utilities AND deregulation Finds records where both terms are mentioned. OR building OR structure Finds records where either one or both of the terms are present. Useful for synonyms. NOT utilities NOT deregulation Finds records where the first term is present and then excludes all records in which the second term appears. W/n pig* w/2 pipe* Finds records where the two terms have no more than n (number of) words between them. ADJ channel ADJ tunnel Finds records in which the two terms are adjacent, in the order specified. W/0 deregulat* W/0 utility Finds records where the terms are adjacent, in either order. NEAR deregulat* near utility Use for relevance ranking. Works like AND (up to 100 words apart), but records where the terms are closer together will be listed first.
