Google is unfriendly to searching for verbatim strings with characters like $ and #. Is there a search engine that supports searching for verbatim strings? Try http://www.google.com/codesearch Just remember that it's a REGEXP language, so to search for $value, use \$value. For example: http://www.google.com/codesearch?hl=en&lr=&q= \%24value&sbtn=Search this one would be cool if more was covered.... http://start.gotapi.com/ or http://www.gotapi

I was wondering whether search engines respect the HTTP header field Content-Location . This could be useful, for example, when you want to remove the session ID argument out of the URL: GET /foo/bar?sid=0123456789 HTTP/1.1 Host: example.com … HTTP/1.1 200 OK Content-Location: http://example.com/foo/bar … Clarification: I don’t want to redirect the request, as removing the session ID would lead to a completely different request and thus probably also a different response. I just want to state that the enclosed response is also available under its “main URL”. Maybe my example was not a good

i'm pretty new to elasticsearch and i want to use synonyms, i added these lines in the configuration file: index : analysis : analyzer : synonym : type : custom tokenizer : whitespace filter : [synonym] filter : synonym : type : synonym synonyms_path: synonyms.txt then i created an index test: "mappings" : { "test" : { "properties" : { "text_1" : { "type" : "string", "analyzer" : "synonym" }, "text_2" : { "search_analyzer" : "standard", "index_analyzer" : "synonym", "type" : "string" }, "text_3" : { "type" : "string", "analyzer" : "synonym" } } } } and insrted a type test with this data: {

Are there any ressources on what the parameters in a Google query mean? Any analysis how the Google search pages work internally? Examples would be http://www.google.com/#hl=en&source=hp&q=lol&aq=f&aqi=&aql=&oq=&fp=45675624562456 or http://www.google.com/url?sa=t&source=web&ct=res&cd=11&ved=KJSGHFKSDJF&url=sfdgagasdgasdgasgasg&rct=j&q=fghthwrteghedgf&ei=asdfasdfsa&usg=asdfasdfasf q=searchstring is the search string source=something is where the search originated (www.google.com webpage, Google Toolbar, Quick Search of various browsers) ie=utf8 input encoding oe=utf8 output encoding rls=en

How Would the Reverse Image Search Engines like TinEye Work ? I mean what parameters are required to do an image search ? Don't know if TinEye use exactly this one, but SURF is a commonly used algorithm for this purpose. Here you can see an usage example in Mathematica where a partial matching of images is used to compose a landscape: database: Generaly you have set of images that are collected from web sites. For each image extract key features (SURF, SIFT, whatever) in a form of numerical vectors associated to each image. Vectors are stored in searchable database. When you give image to

I read some articles on Internet, some said that search engine like Google and Bing don't care about HTML Meta Tags any more. Should I still need to maintain the HTML Meta Tags in my website properly? Thanks! Are meta tags critical? Every search engines emphasizes meta tags differently. Google doesn't let the public know how it uses meta tags. I have noticed that a lot of websites show up on the first page of Google for specific subjects and yet they don't have any keyword or description tags. So don't let anybody fool you by exaggerating how important they are for Search Engine Optimization.
