Search Quick help

Psitri search use dtSearch syntax and it supports three types of search requests:

1 Any Words

An "any words" search is any sequence of text, like a sentence or a question.
In an "any words" search, use quotation marks around phrases, put

+ in front of any word or phrase that is required, and
- in front of a word or phrase to exclude it.

Examples:
"therapeutic mechanisms" -Alcoholism +"mental patients"

2 All words

An "all words" search request is like an "any words" search except that all of the words in the search request must be present for a document to be retrieved.

3 Boolean search

A "boolean" search request consists of a group of words, phrases, or macros linked by connectors such as AND and OR that indicate the relationship between them.

Examples:

adults and children

schizophrenia or acute

schizophrenia w/5 catatonic - schizophrenia must occur within 5 words of catatonic

schizophrenia not w/5 catatonic - schizophrenia must occur, but not within 5 words of catatonic

schizophrenia and not catatonic - only schizophrenia must be present

SN contains smith - the author field name must contain smith

If you use more than one connector, you should use parentheses to indicate precisely what you want to search for.

For example, schizophrenia and catatonic or catatonic shizophrenia could mean (shizophrenia and catatonic) or catatonic shizophrenia, or it could mean shizophrenia and (catatonic or shizophrenia).


Note, that "Noise words", such as "if" and "the", are ignored in searches.

Search terms may include the following special characters:

? - matches any character

= - matches any single digit

* - matches any number of characters

% - fuzzy search

# - phonic search

~ - stemming

& - synonym search

~~ - numeric range

Special character Examples:

schizo* would match schizo, etc.

*neuro* would match neuroleptics, neurosis, etc.

neuro? would match neuros but not neuroses.

pl*o would match placebo, etc.

ANP 400~~500
