    • Generating a document index comprises: obtaining a document to be indexed; determining whether each monadic partition obtained from the document is a filter character and if so, forming a polynary partition with the monadic partition and at least one adjacent monadic partition and indexing the polynary partition, otherwise, indexing the monadic partition. Querying data comprising: receiving a data query, determining whether each monadic partition obtained from the data query is a filter character and if so, forming a polynary partition with the monadic partition and at least one adjacent monadic partition and using the polynary partition to obtain search results, otherwise, using the monadic partition to obtain search results; and combining search results to form a final query search result.
    • 生成文档索引包括:获取要索引的文档; 确定从文档获得的每个单体分区是否是过滤器字符,如果是,则使用单体分区和至少一个相邻单体分区形成多项式分区并索引多项式分区,否则索引单体分区。 查询数据,包括:接收数据查询,确定从数据查询获取的每个单体分区是否是过滤字符,如果是,则使用单体分区和至少一个相邻单体分区形成多项式分区,并使用多重分区获得搜索 结果,否则,使用monadic分区获取搜索结果; 并组合搜索结果以形成最终查询搜索结果。

    • Generating a document index comprises: obtaining a document to be indexed; performing a monadic partition operation on the document to obtain a plurality of monadic partitions; and for each monadic partition in the plurality of monadic partitions: determining whether said each monadic partition is a filter character; in the event said each monadic partition is a filter character, forming a polynary partition by combining the monadic partition with at least one other monadic partition adjacent to the monadic partition, and indexing the polynary partition; and in the event that the monadic partition is not a filter character, indexing the monadic partition. Querying data comprising: receiving a data query; performing a monadic partition operation on the data query to obtain a plurality of monadic partitions; and for each monadic partition in the plurality of monadic partitions: determining whether said each monadic partition is a filter character; in the event that the monadic partition is a filter character, forming a polynary partition by combining the monadic partition with at least one monadic partition adjacent to the monadic partition, and searching a preset index using the polynary partition to obtain a search result corresponding to the polynary partition; and in the event that the monadic partition is not a filter character, searching the preset index using the monadic partition to obtain a search result corresponding to the monadic partition; and combining the search results to form a final query search result.
    • 生成文档索引包括:获取要索引的文档; 对所述文档执行单一分区操作以获得多个单一分区; 并且对于所述多个单体分区中的每个单体分区:确定所述每个单体分区是否是过滤器字符; 在所述每个单体分区是过滤器字符的情况下,通过将所述单体分区与与所述单体分区相邻的至少一个其它单体分区组合并且对所述多项式分区进行索引来形成多项式分区; 并且在monadic分区不是过滤器字符的情况下,对单一分区进行索引。 查询数据包括:接收数据查询; 对所述数据查询执行单一分区操作以获得多个单一分区; 并且对于所述多个单体分区中的每个单体分区:确定所述每个单体分区是否是过滤器字符; 在所述单体分区是过滤字符的情况下,通过将所述单体分区与与所述单体分区相邻的至少一个单体分区组合来形成多项式分区,以及使用所述多项式分区来搜索预设索引以获得对应于所述单体分区的搜索结果 多重分区 并且在单体分区不是过滤器字符的情况下,使用单体分区搜索预设索引以获得与单体分区相对应的搜索结果; 并组合搜索结果以形成最终查询搜索结果。
