Free search tool software for linux

Web search is provided with Yahoo! Search Web Services. Okapibar consists of a keyword input, search engine buttons, and function buttons. The search engine button selects YahooCPM or Yahoo. The function buttons are a highlight button to change the background color of words same as the key words, a compact button to change between one line and two-line layout, and a script button to show that Javascript is disable during the search in CPM.

Basic Local Alignment Search Tool is a set of similarity search programs designed to explore all of the available sequence databases regardless of whether the query is protein or DNA.
It uses a heuristic algorithm which seeks local as opposed to global alignments, and is therefore able to detect relationships among sequences which share only isolated regions of similarity.
It can be run locally as a full executable, and can be used to run BLAST searches against private, local databases, or downloaded copies of the NCBI databases. It runs on Mac OS, Win32, LINUX, Solaris, IBM AIX, SGI, Compaq OSF, and HP- UX systems.
Main features:
Nucleotide
- Quickly search for highly similar sequences (megablast)
- Quickly search for divergent sequences (discontiguous megablast)
- Nucleotide-nucleotide BLAST (blastn)
- Search for short, nearly exact matches
- Search trace archives with megablast or discontiguous megablast
Protein
- Protein-protein BLAST (blastp)
- Position-specific iterated and pattern-hit initiated BLAST (PSI- and PHI-BLAST)
- Search for short, nearly exact matches
- Search the conserved domain database (rpsblast)
- Protein homology by domain architecture (cdart)
Translated
- Translated query vs. protein database (blastx)
- Protein query vs. translated database (tblastn)
- Translated query vs. translated database (tblastx)
Genomes
- Human, mouse, rat, chimp cow, pig, dog, sheep, cat
- Chicken, puffer fish, zebrafish
- Environmental samples
- Protozoa
- Insects, nematodes, plants, fungi, microbial genomes, other eukaryotic genomes
Special
- Search for gene expression data (GEO BLAST)
- Align two sequences (bl2seq)
- Screen for vector contamination (VecScreen)
- Immunoglobin BLAST (IgBlast)
- SNP BLAST
Meta
- Retrieve results

nautilus-search-tool is a Nautilus extension to have "search files" on popup menu.

Search::Tools::XML are methods for playing nice with XML and HTML.

SYNOPSIS

use Search::Tools::XML;

my $class = Search::Tools::XML;

my $text = the "quick brown" fox;

my $xml = $class->start_tag(foo);

$xml .= $class->utf8_safe( $text );

$xml .= $class->end_tag(foo);

# $xml: the "quick brown" fox

$class->escape( $xml );

# $xml: the "quick brown" fox

$class->unescape( $xml );

# $xml: the "quick brown" fox

my $plain = $class->no_html( $xml );

# $plain eq $text

Search::Tools::XML provides utility methods for dealing with XML and HTML. There isnt really anything new here that CPAN doesnt provide via HTML::Entities or similar modules. The difference is convenience: the most common methods you need for search apps are in one place with no extra dependencies.

NOTE: To get full UTF-8 character set from chr() you must be using Perl >= 5.8. This affects things like the unescape* methods.

With this service menu you will be able to search into directory by right-clicking on it. Search Into Directory starts a kfind window (part of kdebase) ready to search into the selected directory.

Note : This servicemenu is in fact duplicated of an existing one on kde-apps. So Ive removed mine and I wont maintain it. Youll find another one named Find in Folder

Search::Tools::Snipper is a Perl module to extract keywords in context.

SYNOPSIS

my $query = [ qw/ quick dog / ];
my $text = the quick brown fox jumped over the lazy dog;

my $s = Search::Tools::Snipper->new(
occur => 3,
context => 8,
word_len => 5,
max_chars => 300,
query => $query
);

print $s->snip( $text );

Search::Tools::Snipper extracts keywords and their context from a larger block of text. The larger block may be plain text or HTML/XML.

DGS Search was created to provide an easy to install search utility capable of handling filesystem and database searches on UNIX and Windows based platforms.

DGS Search is aimed at supporting the small to medium sized web site.

Search::Tools::Keywords is a Perl module to extract keywords from a search query.

SYNOPSIS

use Search::Tools::Keywords;
use Search::Tools::RegExp;

my $query = the quick fox color:brown and "lazy dog" not jumped;

my $kw = Search::Tools::Keywords->new(
stopwords => the,
and_word => and,
or_word => or,
not_word => not,
stemmer => &your_stemmer_here,
ignore_first_char => +-,
ignore_last_char => ,
word_characters => $Search::Tools::RegExp::WordChar,
debug => 0,
phrase_delim => ",
charset => iso-8859-1,
lang => en_US,
locale => en_US.iso-8859-1
);

my @words = $kw->extract( $query );
# returns:
# quick
# fox
# brown
# lazy dog

Do not confuse this class with Search::Tools::RegExp::Keywords.

Search::Tools::Keywords extracts the meaningful words from a search query. Since many search engines support a syntax that includes special characters, boolean words, stopwords, and fields, search queries can become complicated. In order to separate the wheat from the chafe, the supporting words and symbols are removed and just the actual search terms (keywords) are returned.

This class is used internally by Search::Tools::RegExp. You probably dont need to use it directly. But if you do, read on.
