org.apache.lucene.queryparser.classic.ParseException: Cannot parse

Asked 2022-Mar-21 at 15:41

I'm developing my own service based on Apache Lucene. This is a spring server, on the endpoint of which the search request comes - the fields to search for, and their values. This query needs to be parsed in Apache Lucene query, and then sent to the search facade. But here's the bad luck - When I try to stresstest my service (I'm testing with jmeter - 100 threads, each of which performs 100 request operations), I get an execption:

It turned out that queryParser is not thread-safe - inside it has states, access to which from several threads is not synchronized. Therefore, I came to use own queryParser for each request, and not use the previously created one.

In GeoMesa there is not currently an option to persist or pre-calculate enumerations; generally they would be too large to store efficiently.

You might explore persisting them separately, or using a local cache such as Guava.

JavaFX and Lucene

Asked 2021-Dec-01 at 08:19

I am creating a search engine kind of project where i have to make a UI in JavaFX and use Apache Lucene for the queries. I am in a stage where the UI in JavaFX works perfectly on its own(without calling any Lucene methods) and the queries for the Lucene also work fine on its own(in a separate java project). When I try to combine the two by creating an Object of Lucene into the action performed when I press the ENTER button it crashes hard and the exception is far from confusing.

I am providing the code for both my Window and my LuceneTester classes and the exception thrown.

Main class:

Answered 2021-Nov-30 at 16:13

The ClassNotFoundException: org.apache.lucene.queryparser.classic.ParseException means that there is a missing Dependency from Lucene, so you should check your build-tools setup.

But it also means that an Exception occurred so you might want to doublecheck if the Lucene only Code really works.

Lucene: How to search by specific term

Asked 2021-Aug-31 at 20:21

I'm trying to do a Lucene search by a specific string term.
Eg: I had the tags 1-"Hello World", 2-"Hello, Steve", 3-"Helloween" and finally 4-"Hello" if I look for the last tag (hello), Lucene will bring all tags, because all of them had "hello" at some point. I need an operator or a logic that makes the search without "like".

There is a way to avoid this using the clause "must_not" (- operator) and the query will be: term:hello -term:world. But this is not the case, cause I will need to find all other words that should not be in search.

Answered 2021-Aug-27 at 17:00
