There are three search methods in RENVS: "exact phrase", "some words" and "all the words". In all cases, RENVS utilizes automatic mechanisms to determine which are the pages that better respond to the query, trying to display first the most important pages for the user.

The method "exact phrase" only selects documents that contain the phrase in the query, word by word and in the same order

The method"some words" selects documents that contain at least one of the words in the query. In this method the more you include words related to the issue you are searching the better the results obtained.

The method "all the words" selects the documents that contains all the words in the query .

Specify your search The more specific your search the more relevant the pages you'll find. For example, if you are looking for some particular water treatment method do no limit yourself to write "water treatment", but search for "water disinfection" or "water filtration" or "ozonation, "desalinization" etc.

Select a search method The selection of a search method is directly related to the type of information you are looking for.

Use "an exact phrase" If you know an exact phrase in the document you are looking for, like the title of the article, the name of the author use "the exact phrase method"

Reformulate the search when necessary You can reformulate your query in the case it does not return results. The first measure is verifying if there are some spelling errors. If that is not the problem, you can utilize synonyms or use the"some words method" with a larger number of search terms related with the issue you are interested in.
