These operators specify the location of each of your search terms in relation to each other within a document.
To find words which occur next to each other as a phrase, just type the words as you would normally. In ISYS search syntax, there is no need to enclose phrases in quotes.
The retrieved documents must contain both terms, and the second term must follow the appearance of the first. The second term can be anywhere in the document as long as it occurs after the first.
The retrieved documents must contain both search terms occurring in pairs. That is, the second term must immediately follow the first if a document is to be retrieved, without a repeated occurrence of the first term. If the first term occurs multiple times before the second term, then it is the inner-most pair which is selected.
The retrieved documents must contain the first term in a paragraph, beginning with the second term.
If Named Sections have been created, a pop-up list may
appear when you use this function. Select the desired Named Section from the list to add it to the search.
Similar to IN, it is best to use this operator when searching for multiple terms in a field. The retrieved documents must contain the latter term(s) in a paragraph, beginning with the first term. Example: AUTHOR CONTAINS SMITH OR JONES OR WILLIAMS.
The retrieved documents will contain the first search term specified, and it may or may not occur in a paragraph beginning with the second term. However, any instances where the first term does occur in the paragraph beginning with the second term will be considered more relevant. Example: SMITH ESPIN AUTHOR, finds Smith anywhere, but gives preference to those occurrences where Smith is the author.
Retrieved documents must contain a paragraph beginning with the specified search term, for example LABEL ABSTRACT
Retrieved documents must contain the following subexpression occuring in the file name (and document file name indexing must be enabled in the index configuration). For example, FILENAME SHUTTLE.
Both search terms must occur within the specified number of paragraphs of each other. Placing a number between the lines indicates the number of paragraphs separating each term.
Both search terms must appear within the same paragraph. The order of appearance within the paragraph is not relevant. Placing a number between the lines indicates the number of words separating phrases.
The following sub-expression may only occur within the metadata portion of the document, for example "CAT AND METAONLY (DOG OR LION)". Searching only within metadata not only provides for highly accurate queries, but can also provide substantial performance benefit if the search term has many undesired occurrences in the non-meta portion of the document.
Similar to METAONLY, but the following sub-expression must not occur in the metadata.
