Dear Shashi,
As I learned, big data, such as Lucene index, was not suitable to be
updated frequently. Frequent updating must affect the performance and
consistency when Lucene index must be replicated in a large scale cluster.
It is expected such a search engine must work in a write-once
You can update the document in the index quite frequently. IDNK what
your requirement is, another option would be to boost query time.

Dear Shashi,
Thanks so much for your reply!
However, I think the value of PageRank is not a static one. It must update
on the fly. As I know, Lucene index is not suitable to be updated too
frequently. If so, how to deal with that?
Best regards,

Dear all,
I am using SolrJ to implement a system that needs to provide users with
searching services. I have some questions about Solr searching as follows.
As I know, Lucene retrieves data according to the degree of keyword
matching on text field (partial matching).
But, if I search data by
Solr is kind of retrieval step, you can customize the score formula in Lucene.
But it supposes not to be too complicated, like it's better can be
factorization. It also regards to the stored information, like TF,DF,position,
etc. You can do 2nd phase rerank to the top N data you have got.

Hi, Kai,
Thanks so much for your reply!
If the retrieving is done on a string field, not a text field, a complete
matching approach should be used according to my understanding, right? If
so, how does Lucene rank the retrieved data?
Best regards,
Bing

Lucene has a mechanism to boost up/down documents using your custom
ranking algorithm. So if you come up with something like Pagerank
you might do something like doc.SetBoost(myboost), before writing to index.
