摘要： An optical filter is disclosed, including a first optical filter adapted to receive a first optical signal including an optical carrier frequency and a plurality of interference signal components. The first filter produces an output signal at the optical carrier frequency and a reflection signal. The output signal is split into a peak detection path signal and a re-insertion path signal. An optical power detector converts the peak detection path signal into an electrical control signal and aligns the optical carrier frequency to a resonance frequency of the first filter to maximize the power of the optical carrier frequency. A second optical filter receives the reflection signal and selects at least one spectral component while rejecting other spectral components and outputs a filtered signal that carries the selected spectral component. A signal combiner receives and combines the filtered signal and the re-insertion path signal.

摘要： Information retrieval systems such as web search systems locate documents amongst millions and even billions of possible documents on the basis of query terms. In order to achieve this document indexes are created. We propose creating new fields in the documents to store feedback information. This information comprises query terms used in a particular search as well as information about whether a particular document retrieved is given positive or negative feedback for example. Indexes are created on the basis of this feedback information in addition to other available information. As a result relevance of search results is improved. Multiple fields of information are available for given documents (such as abstract fields, title fields, anchor text fields as well as our feedback fields). Any search algorithm which deals with multiple fields as well as multiple query terms and which provides for differential weighting of document fields is used.
摘要翻译：诸如网络搜索系统之类的信息检索系统基于查询条件在数百万甚至数十亿的可能的文档之间找到文档。为了实现这个文件索引的创建。我们建议在文档中创建新的字段来存储反馈信息。该信息包括在特定搜索中使用的查询词，以及关于被检索的特定文档是否被给予正或负反馈的信息。索引是基于此反馈信息创建的，除了其他可用信息。因此，搜索结果的相关性得到改善。多个信息领域可用于给定的文档（例如抽象字段，标题字段，锚文本字段以及我们的反馈字段）。使用任何处理多个字段的搜索算法以及多个查询项，并提供文档字段的差分加权。

An apparatus may include an enhanced search component operative to receive a search query and provide ranked search results responsive to the search query. The enhanced search component may comprise a resource search module operative to search for resources using multiple search terms from the search query, and output a set of resources having some or all of the search terms. The enhanced search component may also comprise a proximity generation module communicatively coupled to the resource search module, the proximity generation module operative to receive the set of resources, retrieve search term position information for each resource, and generate a proximity feature value based on the search term position information. The enhanced search component may further comprise a resource ranking module communicatively coupled to the resource search module and the proximity generation module, the resource ranking module to receive the proximity feature values, and rank the resources based in part on the proximity feature values. Other embodiments are described and claimed.

摘要： A field-weighted search combines statistical information for each term across document fields in a suitably weighted fashion. Both field-specific term frequencies and field and document lengths are considered to obtain a field-weighted document weight for each query term. Each field-weighted document weight can then be combined in order to generate a field-weighted document score that is responsive to the overall query.
