This page describes the search syntax available for the text index (e.g. authors, titles, abstracts, full text ,...).
Word list
You can type a string of words, separated by spaces, without connectors between words. In this case, the search engine will translate spaces as the AND connector.
- Your query:
- processus sédimentaires
- Data available in the database :
- ...morphologie et processus sédimentaires récents...
...l'expulsion des fluides sédimentaires sur le plancher sous-marin... - Results :
- ...morphologie et processus sédimentaires récents...
Expression
Using quotation marks will allow you to find an expression. Therefore you can, if you know the exact sequence of words in the document you are looking for, eliminate noise for the answers.
- Your query :
- "algal blooms"
- Données stockées dans la base de données :
- ... Seasonal green algal blooms (Ulva lactuca ) are observed along Brittany coasts...
... large phytoplanktonic blooms were induced in ponds. Algal supplement was clearly ... - Results :
- ... Seasonal green algal blooms (Ulva lactuca ) are observed along Brittany coasts...
Boolean connectors
To narrow or widen your search, you can also use the Boolean connectors AND, OR and ANDNOT. Those operators can be combined with parentheses.
- Examples :
-
aquaculture* AND ( dicentrarchus OR "sea bass" )
( "Satellite sensing" OR "remote sensing" ) AND (ocean OR sea) - Warning, if you do not use parentheses the search engine will attribute the highest priority to portions linked by the connectors AND or ANDNOT. For example, the question "laser OR neutron ANDNOT support", is interpreted as :
- laser OR (neutron ANDNOT support)
- Please note that this request does not have the same meaning as the following request :
- (laser OR neutron) ANDNOT support
Those 2 questions bring up 2 different results. Also, if you use several different connectors for the same request, we advice you to use parentheses to specify priority strings without ambiguity.
Truncation
Truncation (*) allows you to find a word by using the first or last letters of the word. So, if you type the character * at the beginning (example: *puter), the search engine will bring up all words ending with that sequence (example: computer, transputer).
