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.
