The aim of FreeFullPDF.com is to increase the visibility and ease of use of open access scientific journals, theses, posters and patents. All scientific subjects are covered and all content are freely available in PDF format.

FreeFullPDF performs full-text search in PDF files (title, abstract, authors, materials and methods, results, conclusion, bibliographies…). With FreeFullPDF, you can easily and quickly find the scientific information you want through more than 80 million of PDF files.

The OR operator

FreeFullPDF 's default behavior is to consider all the words in a search. If you want to specifically allow either one of several words, you can use the OR operator.

Example: DNA sequencing OR sequencer

Terms you want to exclude (-)

Attaching a minus sign immediately before a word indicates that you do not want pages that contain this word to appear in your results. The minus sign should appear immediately before the word and should be preceded with a space. The - sign can be used to exclude more than just words.

Example: DNA sequencing -proteins -peptides

Phrase search ("")

By putting double quotes around a set of words, you are telling FreeFullPDF to consider the exact words in that exact order without any change.

Example: "DNA Sequencing by enzymatic method"

Fill in the blanks (*)

The *, or wildcard, is a little-known feature that can be very powerful. If you include * within a query, it tells FreeFullPDF to try to treat the star as a placeholder for any unknown term(s) and then find the best matches.

Example: "DNA Sequencing by * method" will give you DNA sequencing by dideoxy method, DNA sequencing by the Sanger method, DNA sequencing by ligation-mediated PCR method, DNA sequencing by hybridization method …

Search in title

If you include [intitle:] in your query, FreeFullPDF will restrict the results to documents containing that word in the title tag. If you want to search for more than one keyword use "allintitle". If you start a query with [allintitle:] FreeFullPDF will search only those pages with all of the query words with in the title tag.

Example: allintitle:DNA sequencing

Scientific Synonyms

Users' search queries are automatically expanded with synonyms/acronyms.

Example: Search query "DNA" has the following equivalent alternatives: "deoxyribonucleic acid”, "desoxyribonucleic acid " or "ADN"

Databases

At present, about 10.000 sources of free articles (journals, open archives...) are indexed in FreeFullPDF database.
