how to write my first solr query
Hello, I would like to find all documents that have say foo bar with a filter to remove any cases where foo bar is prefixed with things like cat, a, ... I am ok with a document that has cat foo bar and foo bar, but if it only has cat foo bar then I don't want it while if it has foo bar I want it. I looked at span queries but was not able to come up with how to phrase this. Any pointers would be great!

Re: how to write my first solr query
Hi Evan, Confusing use case :) You don't want foo bar is prefixed with cat ? But you are ok with a document that has cat foo bar Isn't this contradiction?

Re: how to write my first solr query
Hello, Here is a better use case Documents A, B, C, and D A: dear foo bar hello B: dear cat foo bar hello C: dear cat foo bar hello foo bar D: dear car foo bar I have a dictionary of items outside of solr foo bar and cat foo bar And associated with each item is the set of suffix's of that item So I know that foo bar has cat foo bar as a suffix I would like to search my corpus of documents A, B, C and D And just get documents that contain foo bar and not the ones that contain cat foo bar So if I searched on foo bar but not cat foo bar I want to get documents A, C, D But not B which does not have just foo bar but has cat foo bar. I am ok with C as it has a foo bar that is not prefixed with cat. Does this make sense? I see that the (foo bar and not cat foo bar) would not work as it would miss document C. Or at least I think it would.

RE: how to write my first solr query
Hi Evan, If I understand correctly, a document has to have at least one foo bar without having cat in front. A solution would be to use a combination of the ShingleFilterFactory and query for one occurences of foo bar using the termfreq function. https://cwiki.apache.org/confluence/display/solr/Filter+Descriptions#FilterDescriptions-ShingleFilter https://cwiki.apache.org/confluence/display/solr/Function+Queries The number of shingles depends on how many terms are in the query and how many terms cannot be prefixed. It might be easier to just retrieve all the documents which contain the phrase and process the results outside of Solr. If you could shed some more light on what you are trying to accomplish, maybe we can help you find an even better solution to fit your problem.

RE: how to write my first solr query
Hello, Thank you! I will try out what you suggested and post back once I know more. yes given things like cat foo bar house foo bar foo bar I want to know when the term foo bar (but not the prefix cases I specify) exists in my documents.

Re: AW: My First Solr
Do you see if the document update is sucessful? When you start solr with java -jar start.jar for the example, Solr will list the the document id of the docs that you are adding and tell you how long the update took. A simple but brute force method to findout if a document has been commited is to stop the server and then restart it. You can also use the solr/admin/stats.jsp page to see if the docs are there. After looking at your query in the results you posted, I would bet that you are not specifying a search field. try searching for anwendung:KIS or id:[1 TO *] to see all the docs in you index.

No, you do not have to reindex. You do have to restart the server.
