The invention discloses a full-text retrieval matching method and system based on a Lucence custom lexicon, and relates to the field of big data search. The method comprises the following steps: in a Lucence search environment, obtaining a search word input by a user in real time, detecting whether a result is searched or not, removing special characters from the search word if no results are searched, and storing into the Lucence custom lexicon; if the result is searched, carrying out word segmentation on the search word, continuously searching a plurality of phrases subjected to the word segmentation, detecting whether the result is searched or not, removing the special characters from the phrases, which can not search the result, subjected to the word segmentation if no results are searched, and storing into the Lucence custom lexicon; if the result is search, recording search time, the search word subjected to the word segmentation and search feedback information, and finally establishing the Lucence custom lexicon which supports Lucence full-text retrieval. According to the search word input by the user, the method can quickly and effectively establish an own customized Lucence custom lexicon.

The invention provides a method for establishing the inter-satellite links of a Beidou navigation system. The method is used for solving the problem in the prior art that the communication cannot be realized due to the fact that a satellite body in a link-establishing planning chart for the preset inter-satellite links of a Beidou navigation system in China breaks down. According to the technical scheme of the invention, firstly, a logical address is set for each satellite in the system. After that, the fault state information of a satellite is added into the information of the Beidou navigation system. In this way, the fault occurring moment of the satellite body can be shown. Based on the fault information delivery policy, all satellites in the system can acquire the state information of a faulty satellite. Meanwhile, the fault state information of the satellite is written into a temporary chart through updating the temporary chart of the link-establishing planning chart. Finally, the updated temporary chart and a node satellite chart are read, so that the new links of the Beidou navigation system are established. The establishing accuracy and the establishing timeliness of the inter-satellite links of the Beidou navigation system are improved.

The invention discloses a distributed file transmission method, a server and private cloud equipment. The method comprises: receiving, by a public server located on a public network, a file acquisition request from a first client; obtaining available transmission nodes in a group virtual space of the public server; and pushing the available transmission node information and the file information of the file to the first transmission node, so that a transfer transmission channel is established between the first transmission node and at least one of the available transmission nodes, the file stored in the available transmission node or a part of the file is transmitted to the first transmission node through the transfer transmission channel, and downloading by the first client is facilitated. In this way, the efficiency and reliability of obtaining the file can be improved.
