| 2011-05-18 21:04 <dfamorato> cedk: ping | ||
| 2011-05-18 21:05 <cedk> dfamorato: pong | ||
| 2011-05-18 21:05 <dfamorato> cedk: Hey there. I have some questions about my GSOC project on full-text search | ||
| 2011-05-18 21:06 <dfamorato> cedk: I've been doing some research on the sphinx search server | ||
| 2011-05-18 21:06 <dfamorato> cedk: and we have mainly 2 ways to index data: Real-Time and Delta(batch) indexing at a constant time | ||
| 2011-05-18 21:07 <dfamorato> cedk: So, since there are major differences on implementation details between these two | ||
| 2011-05-18 21:08 <dfamorato> cedk: I would like your opinion on how the data should be index for tryton... Real-Time or Batch | ||
| 2011-05-18 21:09 <cedk> dfamorato: of course Real-Time is better but what will be the overload of this? | ||
| 2011-05-18 21:10 <dfamorato> cedk: regarding index database ... it says we should expect something from 40% to 70% of the size of the database being indexed | ||
| 2011-05-18 21:11 <dfamorato> cedk; regaring memory, so far I haven't found much information expect the fact that we can declare how much memory can be used by the indexer and the indexer will consume UP TO that limit | ||
| 2011-05-18 21:11 <dfamorato> cedk: then will start writing on the disk | ||
| 2011-05-18 21:12 <dfamorato> cedk; It is also possible with Sphinx to have multiple indexes.... | ||
| 2011-05-18 21:12 <cedk> dfamorato: I think you need to have one index per language | ||
| 2011-05-18 21:12 <dfamorato> cedk: example: one index for products.... 1 for invoices, 1 for party and so on | ||
| 2011-05-18 21:13 <dfamorato> cedk: and when we want to query the index, they are queried in parallel | ||
| 2011-05-18 21:13 <cedk> dfamorato: yes, but I think this should be configured | ||
| 2011-05-18 21:13 <cedk> dfamorato: how do you see how the update of the index will be done in RT? | ||
| 2011-05-18 21:14 <dfamorato> cedk: well... last time I spoke with bertrand... we discussed that ideally we would make a tryton "driver" to be used by sphinx indexer | ||
| 2011-05-18 21:15 <dfamorato> that means, any changes it happens on tryton should be PUSHED to the indexer in order for it to be indexed | ||
| 2011-05-18 21:15 <dfamorato> that's the main difference between the batch indexing and RT | ||
| 2011-05-18 21:16 <dfamorato> cedk: batch processing = we can query for the data we want and then we index it | ||
| 2011-05-18 21:16 <cedk> dfamorato: ok but what will be the cost of the push? Could it be done in separate thread? | ||
| 2011-05-18 21:16 <dfamorato> cedk: RT = the tryton server pushes the data to us | ||
| 2011-05-18 21:17 <dfamorato> cedk: yes, i believe we can do it asynchronously... that way the tryton server does not need to way for saving/pushing any info | ||
| 2011-05-18 21:18 <cedk> dfamorato: so if async is possible, I will prefer the RT way | ||

| 2011-05-18 21:19 <dfamorato> cedk: ok... so we use RT indexing the... point 1 decided.. | ||
| 2011-05-18 21:20 <dfamorato> cedk: now... in order to implement asynchronous, I think i should use queue ... what do you think | ||
| 2011-05-18 21:21 <cedk> dfamorato: why not | ||
| 2011-05-18 21:22 <cedk> dfamorato: but try to keep simple | ||

| 2011-05-18 21:23 <dfamorato> ok... I will do some research for what we can use to glue tryton server messages and sphinx indexer.... | ||
| 2011-05-18 21:23 <dfamorato> cedk: now... regarding multiple languages..... | ||
| 2011-05-18 21:24 <dfamorato> cedk: sphinx uses a process call stemming | ||
| 2011-05-18 21:25 <dfamorato> cedk: which reduces the words to their "root" form | ||
| 2011-05-18 21:25 <dfamorato> cedk: example: happinness = happy lawfull = law and so on | ||
| 2011-05-18 21:26 -!- okko(~okko@dhcp-077-251-140-095.chello.nl) has joined #tryton | ||
| 2011-05-18 21:27 <dfamorato> cedk: using the default sphinx installation packages... it only supports english, czech and russian by default | ||
| 2011-05-18 21:27 <cedk> dfamorato: no other language? | ||
| 2011-05-18 21:28 <dfamorato> cedk: if we need to support additional languages on the stemming process, we need to compile sphinx from source and use the snowball libstemmer library | ||
| 2011-05-18 21:28 <dfamorato> cedk: which then adds support for 13 languages: Danish, Dutch, Finish, French, German, Hungarian, Italia, Norwegian, Portuguese, Romanina, Spanish, Swedish and Turkisg | ||
| 2011-05-18 21:29 <dfamorato> cedk: so I guess i should base my development using the libstemmer then... so it supports the additional languages right ? | ||
| 2011-05-18 21:29 <cedk> dfamorato: yes | ||
| 2011-05-18 21:31 <dfamorato> cedk: ok, now regarding the "tryton-driver" for sphinx... which will "expose" the objects used by the tryton model to be indexed | ||
| 2011-05-18 21:33 <dfamorato> cedk: As it was suggested to me, I was think about using the same concept that the current modules use.. searchable = 1 or 2, so we make the searchable = 1 to be full-text indexes and searchable =2 to be attributes. Attributes can be used for sorting | ||
| 2011-05-18 21:33 <dfamorato> cedk: Attributes are not used as full-text index. | ||
| 2011-05-18 21:34 <dfamorato> cedk: example: let's say we sell books..... author name and book title should be full text... as well as the id/code ... all other data is attribute... | ||
| 2011-05-18 21:35 <cedk> dfamorato: I don't understand the searchable stuff? | ||
| 2011-05-18 21:35 <dfamorato> cedk: so, we can group and sort based on the publication date, cost, and so on | ||
| 2011-05-18 21:36 <cedk> dfamorato: what do you mean by grouping/sorting ? | ||
| 2011-05-18 21:36 <dfamorato> cedk: sorry.. i meant select.... select = 1 creates an index on the current backend..... | ||
| 2011-05-18 21:37 <dfamorato> cedk: i believe we can extend the view of the search fields in order to query only a specific range of dates for example | ||
| 2011-05-18 21:39 <cedk> dfamorato: there is a new GUI interface by bechamel to get just a textbox | ||
| 2011-05-18 21:40 <dfamorato> cedk: on 2.0 ? | ||
| 2011-05-18 21:40 <dfamorato> cedk: speaking about bechamel, when he will be back ? | ||
| 2011-05-18 21:41 <cedk> dfamorato: don't know, he is there most of the time during office time in Europe | ||
| 2011-05-18 21:43 <dfamorato> cedk: must be the timezon difference that i haven't seen him | ||
| 2011-05-18 21:44 <dfamorato> cedk: so I will do more research then about my idea of the tryton-driver for sphix and then I get back to you guys again | ||
| 2011-05-18 21:44 <cedk> dfamorato: yes, you can also send emails | ||
| 2011-05-18 21:44 <cedk> dfamorato: ask bechamel about the new search view in progress | ||
| 2011-05-18 21:44 <dfamorato> cedk: I will | ||
| 2011-05-18 21:45 <dfamorato> cedk: Also... I shoudl focus this development on version 2.0 right | ||

| 2011-05-18 22:30 <hoRn> hi | ||
| 2011-05-18 22:33 <hoRn> I'm searching for an example to define a tree of a One2Many in the form - i don't need all the fields and i have seen such a example in an other model. Anybody has a hint? | ||
| 2011-05-18 22:41 <udono> hoRn: hi, take a look at party/party.xml. There is the included address tree defined. | ||
| 2011-05-18 22:41 <udono> hoRn: <tree string="Addresses" sequence="sequence" ... | ||
| 2011-05-18 22:53 <hoRn> thank you | ||
| 2011-05-18 22:54 <hoRn> ok - nice | ||
| 2011-05-18 22:59 <udono> hoRn: welcome | ||
| 2011-05-18 23:00 <hoRn> udono: and nice to have you in my contacts at xing ;) | ||
| 2011-05-18 23:07 <udono> hoRn: yes | ||
| 2011-05-18 23:13 <hoRn> Yesterday a client asked me, if it is possible to cut the seconds of datetime fields. So I was looking arround and find the code where it is defined in the code of the client. changing this ends in errors, because there are other places where the datetimefields are accesed in tuples with the length of the field with seconds. now I think about a solution for this .... | ||
