Google Panda is a major change to Google's search results ranking algorithm that was first released in February 2011. The change aimed to lower the rank of "low-quality sites" or "thin sites", [1] in particular "content farms", [2] and return higher-quality sites near the top of the search results.
Haridwar, a site for Hindu pilgrimage, 1866 photograph.. Some notable places where Shraadhs are performed for the Pitrs are noted below. At these sites, it became customary for the family pandits (priest) to record each visit of the family, along with their gotra, family tree, marriages, and members present, grouped according to family and hometown.
keeps keys in sorted order for sequential traversing; uses a hierarchical index to minimize the number of disk reads; uses partially full blocks to speed up insertions and deletions; keeps the index balanced with a recursive algorithm; In addition, a B-tree minimizes waste by making sure the interior nodes are at least half full.
Jeff Atwood stated in 2010 that duplicate questions are not seen as a problem but rather they constitute an advantage if such additional questions drive extra traffic to the site by multiplying relevant keyword hits in search engines.
When files with same hashes are found then the file copy is removed and the new file points to the old file. Unlike hard links however, duplicated files are considered to be separate entities and if one of the duplicated files is later modified, then using a system called copy-on-write a copy of that changed file or block is created. The ...
A suffix tree of the letters ATCGATCGA$ In computer science, the longest repeated substring problem is the problem of finding the longest substring of a string that occurs at least twice.
The most general approach to similarity search relies upon the mathematical notion of metric space, which allows the construction of efficient index structures in order to achieve scalability in the search domain. Similarity search evolved independently in a number of different scientific and computing contexts, according to various needs.
A sparse index in databases is a file with pairs of keys and pointers for every block in the data file. Every key in this file is associated with a particular pointer to the block in the sorted data file. In clustered indices with duplicate keys, the sparse index points to the lowest search key in each block.
