Newsgroup auto indexers are programs that search for a large variety of large Usenet newsgroups and identify relevant topics based on the content of the groups. They can be used to obtain any type of data such as newsgroup posts, newsgroup attachments, and user comments. Many newsgroups offer file formats of text or binary format that can easily be indexed by newsgroup indexers.
A newsgroup indexer is commonly installed on the computer that hosts the newsgroups. The newsgroup auto editor, also known as newsreader, has a GUI that allows users to browse groups and extract data into files. Newsgroup indexers allow users to sort their newsgroups based on subject, age, or other criteria. Some newsgroups allow users to restrict certain fields of the newsgroup to prevent retrieval of certain types of information.
An example of newsgroup indexing application is the newsgroup reader. This tool can be used for both casual browsing and extraction of data. Newsgroup readers often come with built in indexers that allow users to retrieve all selected groups or files. Newsgroup indexers are sometimes referred to as newsboard readers. This tool is commonly used by large organizations that maintain newsgroups that are accessible to a wide range of users.
Newsgroup readers are designed to allow users to read and extract all selected files from newsgroups without downloading each message individually. The newsgroup reader allows the user to choose which files to download and/or extract. Newsgroup indexers typically contain a hierarchy of folders that allow users to look for specific types of files. In addition, most newsgroup indexers allow extraction of multiple files from one newsgroup.
There are some newsgroup providers that offer newsgroup auto indexers for free. These free indexers can be configured to search all available types of newsgroups. However, the free versions usually do not have sophisticated features and are quite basic. Advanced users may wish to pay for newsgroup indexer services that provide more detailed information about newsgroups and allow for advanced search options.
Most newsgroup indexers are designed to be used on PCs and laptops. Newsgroup indexers collect meta-data, such as names of users, messages, comments, attachments, dates, times and other related items. The meta-data is then divided into separate files. Some newsgroup directories allow the creation of newsgroup archives. These archive files may be read by any of the indexers, regardless of the program used. Newsgroups allow users to share large files, which is one of the advantages of the newsgroup system.
In addition to reading messages, some newsgroup indexers also have the capability to extract video files from newsgroups. Although not always possible, some newsgroups allow extraction of pictures and music. One drawback of newsgroup downloading is that sometimes personal information, such as usernames and passwords, is found in the newsgroups. However, this can usually be prevented, especially with paid newsgroup indexers.
Some newsgroup indexers, such as newsgroupson, allow users to search for specific newsgroups. Other newsgroup indexers allow users to specify headers to send when sending a message to the newsgroup servers. These headers are used by newsgroup servers to determine if the message should be deleted or forwarded. Most newsgroup indexers use the newsgroup application protocol (APPT) to retrieve and index groups of newsgroups. There are a number of newsgroup software tools that are available to help index messages for users.
Newsgroup indexers can be used to download only certain types of files, which will save bandwidth. Newsgroups can range from individual newsgroups to entire archives of past messages. This allows users to find newsgroups interesting to them without having to scan the entire newsgroup looking for interesting messages. Newsgroup indexers are used for both personal and business purposes. They make browsing newsgroups easy and convenient. The ability to retrieve information from newsgroups allows for an even greater flexibility of using internet services.
Newsgroup indexers are available in a wide range of prices. Indexers based on the LAMP and LAMF technologies are generally more expensive than newsgroup indexers based on the JAVA technology. Some newsgroup indexers have a commercial license while others are designed for free use. Many indexers are capable of retrieving and indexing a variety of file formats including HTML, WML, and RTF.
