- Non-alphanumeric characters (from '-') are stripped.
- All search keyword are used in searching links:
e.g. bioinformatics links directory will search for links that contain all three keywords in title, description, or tags. - You can search for an exact phrase by enclosing the query in quotes:
e.g. "bioinformatics links directory" - e.g. Search query "genomic sequences" dna will search for links containing the phrase "genomic sequences" and dna.
- You can include OR uppercase keyword:
e.g. dna OR rna looks for keywords dna or rna. - You can include - prefix or NOT uppercase keyword to define keywords that should not be included:
e.g. dna OR rna NOT protein (alternatively: dna OR rna -protein) will look for links with keywords DNA or RNA, but not protein
